Do not include without the directory prefix, as this may cause file name conflicts on some systems. Before using ENet, you must call enet_initialize() to initialize the library. Upon program exit, you should call enet_deinitialize() so that the library may clean up any used resources. @code #include int main (int argc, char ** argv) { if (enet_initialize () != 0) { fprintf (stderr, "An error occurred while initializing ENet.\n"); return EXIT_FAILURE; } atexit (enet_deinitialize); ... ... ... } @endcode @section CreateServer Creating an ENet server Servers in ENet are constructed with enet_host_create(). You must specify an address on which to receive data and new connections, as well as the maximum allowable numbers of connected peers. You may optionally specify the incoming and outgoing bandwidth of the server in bytes per second so that ENet may try to statically manage bandwidth resources among connected peers in addition to its dynamic throttling algorithm; specifying 0 for these two options will cause ENet to rely entirely upon its dynamic throttling algorithm to manage bandwidth. When done with a host, the host may be destroyed with enet_host_destroy(). All connected peers to the host will be reset, and the resources used by the host will be freed. @code ENetAddress address; ENetHost * server; /* Bind the server to the default localhost. */ /* A specific host address can be specified by */ /* enet_address_set_host (& address, "x.x.x.x"); */ address.host = ENET_HOST_ANY; /* Bind the server to port 1234. */ address.port = 1234; server = enet_host_create (& address /* the address to bind the server host to */, 32 /* allow up to 32 clients and/or outgoing connections */, 2 /* allow up to 2 channels to be used, 0 and 1 */, 0 /* assume any amount of incoming bandwidth */, 0 /* assume any amount of outgoing bandwidth */); if (server == NULL) { fprintf (stderr, "An error occurred while trying to create an ENet server host.\n"); exit (EXIT_FAILURE); } ... ... ... enet_host_destroy(server); @endcode @section CreateClient Creating an ENet client Clients in ENet are similarly constructed with enet_host_create() when no address is specified to bind the host to. Bandwidth may be specified for the client host as in the above example. The peer count controls the maximum number of connections to other server hosts that may be simultaneously open. @code ENetHost * client; client = enet_host_create (NULL /* create a client host */, 1 /* only allow 1 outgoing connection */, 2 /* allow up 2 channels to be used, 0 and 1 */, 0 /* assume any amount of incoming bandwidth */, 0 /* assume any amount of outgoing bandwidth */); if (client == NULL) { fprintf (stderr, "An error occurred while trying to create an ENet client host.\n"); exit (EXIT_FAILURE); } ... ... ... enet_host_destroy(client); @endcode @section ManageHost Managing an ENet host ENet uses a polled event model to notify the programmer of significant events. ENet hosts are polled for events with enet_host_service(), where an optional timeout value in milliseconds may be specified to control how long ENet will poll; if a timeout of 0 is specified, enet_host_service() will return immediately if there are no events to dispatch. enet_host_service() will return 1 if an event was dispatched within the specified timeout. Beware that most processing of the network with the ENet stack is done inside enet_host_service(). Both hosts that make up the sides of a connection must regularly call this function to ensure packets are actually sent and received. A common symptom of not actively calling enet_host_service() on both ends is that one side receives events while the other does not. The best way to schedule this activity to ensure adequate service is, for example, to call enet_host_service() with a 0 timeout (meaning non-blocking) at the beginning of every frame in a game loop. Currently there are only four types of significant events in ENet: An event of type ENET_EVENT_TYPE_NONE is returned if no event occurred within the specified time limit. enet_host_service() will return 0 with this event. An event of type ENET_EVENT_TYPE_CONNECT is returned when either a new client host has connected to the server host or when an attempt to establish a connection with a foreign host has succeeded. Only the "peer" field of the event structure is valid for this event and contains the newly connected peer. An event of type ENET_EVENT_TYPE_RECEIVE is returned when a packet is received from a connected peer. The "peer" field contains the peer the packet was received from, "channelID" is the channel on which the packet was sent, and "packet" is the packet that was sent. The packet contained in the "packet" field must be destroyed with enet_packet_destroy() when you are done inspecting its contents. An event of type ENET_EVENT_TYPE_DISCONNECT is returned when a connected peer has either explicitly disconnected or timed out. Only the "peer" field of the event structure is valid for this event and contains the peer that disconnected. Only the "data" field of the peer is still valid on a disconnect event and must be explicitly reset. @code ENetEvent event; /* Wait up to 1000 milliseconds for an event. */ while (enet_host_service (client, & event, 1000) > 0) { switch (event.type) { case ENET_EVENT_TYPE_CONNECT: printf ("A new client connected from %x:%u.\n", event.peer -> address.host, event.peer -> address.port); /* Store any relevant client information here. */ event.peer -> data = "Client information"; break; case ENET_EVENT_TYPE_RECEIVE: printf ("A packet of length %u containing %s was received from %s on channel %u.\n", event.packet -> dataLength, event.packet -> data, event.peer -> data, event.channelID); /* Clean up the packet now that we're done using it. */ enet_packet_destroy (event.packet); break; case ENET_EVENT_TYPE_DISCONNECT: printf ("%s disconnected.\n", event.peer -> data); /* Reset the peer's client information. */ event.peer -> data = NULL; } } ... ... ... @endcode @section SendingPacket Sending a packet to an ENet peer Packets in ENet are created with enet_packet_create(), where the size of the packet must be specified. Optionally, initial data may be specified to copy into the packet. Certain flags may also be supplied to enet_packet_create() to control various packet features: ENET_PACKET_FLAG_RELIABLE specifies that the packet must use reliable delivery. A reliable packet is guaranteed to be delivered, and a number of retry attempts will be made until an acknowledgement is received from the foreign host the packet is sent to. If a certain number of retry attempts is reached without any acknowledgement, ENet will assume the peer has disconnected and forcefully reset the connection. If this flag is not specified, the packet is assumed an unreliable packet, and no retry attempts will be made nor acknowledgements generated. A packet may be resized (extended or truncated) with enet_packet_resize(). A packet is sent to a foreign host with enet_peer_send(). enet_peer_send() accepts a channel id over which to send the packet to a given peer. Once the packet is handed over to ENet with enet_peer_send(), ENet will handle its deallocation and enet_packet_destroy() should not be used upon it. One may also use enet_host_broadcast() to send a packet to all connected peers on a given host over a specified channel id, as with enet_peer_send(). Queued packets will be sent on a call to enet_host_service(). Alternatively, enet_host_flush() will send out queued packets without dispatching any events. @code /* Create a reliable packet of size 7 containing "packet\0" */ ENetPacket * packet = enet_packet_create ("packet", strlen ("packet") + 1, ENET_PACKET_FLAG_RELIABLE); /* Extend the packet so and append the string "foo", so it now */ /* contains "packetfoo\0" */ enet_packet_resize (packet, strlen ("packetfoo") + 1); strcpy (& packet -> data [strlen ("packet")], "foo"); /* Send the packet to the peer over channel id 0. */ /* One could also broadcast the packet by */ /* enet_host_broadcast (host, 0, packet); */ enet_peer_send (peer, 0, packet); ... ... ... /* One could just use enet_host_service() instead. */ enet_host_flush (host); @endcode @section Disconnecting Disconnecting an ENet peer Peers may be gently disconnected with enet_peer_disconnect(). A disconnect request will be sent to the foreign host, and ENet will wait for an acknowledgement from the foreign host before finally disconnecting. An event of type ENET_EVENT_TYPE_DISCONNECT will be generated once the disconnection succeeds. Normally timeouts apply to the disconnect acknowledgement, and so if no acknowledgement is received after a length of time the peer will be forcefully disconnected. enet_peer_reset() will forcefully disconnect a peer. The foreign host will get no notification of a disconnect and will time out on the foreign host. No event is generated. @code ENetEvent event; enet_peer_disconnect (peer, 0); /* Allow up to 3 seconds for the disconnect to succeed * and drop any packets received packets. */ while (enet_host_service (client, & event, 3000) > 0) { switch (event.type) { case ENET_EVENT_TYPE_RECEIVE: enet_packet_destroy (event.packet); break; case ENET_EVENT_TYPE_DISCONNECT: puts ("Disconnection succeeded."); return; ... ... ... } } /* We've arrived here, so the disconnect attempt didn't */ /* succeed yet. Force the connection down. */ enet_peer_reset (peer); ... ... ... @endcode @section Connecting Connecting to an ENet host A connection to a foreign host is initiated with enet_host_connect(). It accepts the address of a foreign host to connect to, and the number of channels that should be allocated for communication. If N channels are allocated for use, their channel ids will be numbered 0 through N-1. A peer representing the connection attempt is returned, or NULL if there were no available peers over which to initiate the connection. When the connection attempt succeeds, an event of type ENET_EVENT_TYPE_CONNECT will be generated. If the connection attempt times out or otherwise fails, an event of type ENET_EVENT_TYPE_DISCONNECT will be generated. @code ENetAddress address; ENetEvent event; ENetPeer *peer; /* Connect to some.server.net:1234. */ enet_address_set_host (& address, "some.server.net"); address.port = 1234; /* Initiate the connection, allocating the two channels 0 and 1. */ peer = enet_host_connect (client, & address, 2, 0); if (peer == NULL) { fprintf (stderr, "No available peers for initiating an ENet connection.\n"); exit (EXIT_FAILURE); } /* Wait up to 5 seconds for the connection attempt to succeed. */ if (enet_host_service (client, & event, 5000) > 0 && event.type == ENET_EVENT_TYPE_CONNECT) { puts ("Connection to some.server.net:1234 succeeded."); ... ... ... } else { /* Either the 5 seconds are up or a disconnect event was */ /* received. Reset the peer in the event the 5 seconds */ /* had run out without any significant event. */ enet_peer_reset (peer); puts ("Connection to some.server.net:1234 failed."); } ... ... ... @endcode */ enet-1.3.17/docs/mainpage.dox0000644000175000017500000000317313754264327014100 0ustar leelee/** @mainpage ENet ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol).

ENet does not use any significant global variables, the vast majority of state is encapsulated in the ENetHost structure. As such, as long as the application guards access to this structure, then ENet should operate fine in a multi-threaded environment. @section Q2 Isn't ENet just re-inventing TCP?! What's the point? In a perfect world, that would be true. But as many have found, using TCP either in lieu of or in conjunction with UDP can lead to all kinds of nightmares. TCP is a good, solid protocol, however it simply isn't up to the task of real-time games. Too much of TCP's implementation dictates a policy that isn't practical for games. If you want to use TCP, then do so -- this library is for people that either don't want to use TCP or have tried and ended up being discouraged with the performance. */ enet-1.3.17/docs/html/0000755000175000017500000000000013754264357012546 5ustar leeleeenet-1.3.17/docs/html/structENetCompressor.html0000644000175000017500000002306513754264357017617 0ustar leelee ENet: ENetCompressor Struct Reference

peerCountthe maximum number of peers that should be allocated for the host.
channelLimitthe maximum number of channels allowed; if 0, then this is equivalent to ENET_PROTOCOL_MAXIMUM_CHANNEL_COUNT
incomingBandwidthdownstream bandwidth of the host in bytes/second; if 0, ENet will assume unlimited bandwidth.
outgoingBandwidthupstream bandwidth of the host in bytes/second; if 0, ENet will assume unlimited bandwidth.
Returns
the host on success and NULL on failure
Remarks
ENet will strategically drop packets on specific sides of a connection between hosts to ensure the host's bandwidth is not overwhelmed. The bandwidth parameters also determine the window size of a connection which limits the amount of reliable packets that may be in transit at any given time.

◆ enet_host_destroy()

void enet_host_destroy ( ENetHost *  host)

#include <host.c>

Destroys the host and all resources associated with it.

Parameters
hostpointer to the host to destroy

◆ enet_host_flush()

void enet_host_flush ( ENetHost *  host)

#include <protocol.c>

Sends any queued packets on the host specified to its designated peers.

Parameters
hosthost to flush
Remarks
this function need only be used in circumstances where one wishes to send queued packets earlier than in a call to enet_host_service().

◆ enet_host_service()

int enet_host_service ( ENetHost *  host,
ENetEvent *  event,
enet_uint32  timeout 
)

#include <protocol.c>

Waits for events on the host specified and shuttles packets between the host and its peers.

Parameters
hosthost to service
eventan event structure where event details will be placed if one occurs if event == NULL then no events will be delivered
timeoutnumber of milliseconds that ENet should wait for events
Return values
>0 if an event occurred within the specified time limit
0if no event occurred
<0 on failure
Remarks
enet_host_service should be called fairly regularly for adequate performance

enet_uint16 port
 

Detailed Description

Portable internet address structure.

The host must be specified in network byte-order, and the port must be in host byte-order. The constant ENET_HOST_ANY may be used to specify the default server host. The constant ENET_HOST_BROADCAST may be used to specify the broadcast address (255.255.255.255). This makes sense for enet_host_connect, but not for enet_host_create. Once a server responds to a broadcast, the address is updated from ENET_HOST_BROADCAST to the server's actual IP address.

ENet  v1.3.17
Reliable UDP networking library
Installation

ENet should be trivially simple to integrate with most applications.

First, make sure you download the latest source distribution at Downloads.

Unix-like Operating Systems

If you are using an ENet release, then you should simply be able to build it by doing the following:

./configure && make && make install

If you obtained the package from github, you must have automake and autoconf available to generate the build system first by doing the following command before using the above mentioned build procedure:

autoreconf -vfi

Solaris and BSD

When building ENet under Solaris, you must specify the -lsocket and -lnsl parameters to your compiler to ensure that the sockets library is linked in.

Microsoft Windows

You may simply use the included "enet.lib" or "enet64.lib" static libraries. However, if you wish to build the library yourself, then the following instructions apply:

There is an included MSVC 6 project (enet.dsp) which you may use to build a suitable library file. Alternatively, you may simply drag all the ENet source files into your main project.

You will have to link to the Winsock2 libraries, so make sure to add ws2_32.lib and winmm.lib to your library list (Project Settings | Link | Object/library modules).

Load the included enet.dsp. MSVC may ask you to convert it if you are on a newer version of MSVC - just allow the conversion and save the resulting project as "enet" or similar. After you build this project, it will output an "enet.lib" file to either the "Debug/" or "Release/" directory, depending on which configuration you have selected to build. By default, it should produce "Debug/enet.lib".

You may then copy the resulting "enet.lib" file and the header files found in the "include/" directory to your other projects and add it to their library lists. Make sure to also link against "ws2_32.lib" and "winmm.lib" as described above.

DLL

If you wish to build ENet as a DLL you must first define ENET_DLL within the project (Project Settings | C/C++ | Preprocessor | Preprocessor definitions) or, more invasively, simply define ENET_DLL at the top of enet.h.

Frequently Answered Questions

Is ENet thread-safe?

ENet does not use any significant global variables, the vast majority of state is encapsulated in the ENetHost structure. As such, as long as the application guards access to this structure, then ENet should operate fine in a multi-threaded environment.

Isn't ENet just re-inventing TCP?! What's the point?

In a perfect world, that would be true. But as many have found, using TCP either in lieu of or in conjunction with UDP can lead to all kinds of nightmares. TCP is a good, solid protocol, however it simply isn't up to the task of real-time games. Too much of TCP's implementation dictates a policy that isn't practical for games. If you want to use TCP, then do so – this library is for people that either don't want to use TCP or have tried and ended up being discouraged with the performance.

ENet  v1.3.17
Reliable UDP networking library
ENet

ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol).The primary feature it provides is optional reliable, in-order delivery of packets.

ENet omits certain higher level networking features such as authentication, lobbying, server discovery, encryption, or other similar tasks that are particularly application specific so that the library remains flexible, portable, and easily embeddable.

    int enet_peer_throttle ( ENetPeer *  peer,
    enet_uint32  rtt 
    )

    #include <peer.c>

    ◆ enet_peer_throttle_configure()

    void enet_peer_throttle_configure ( ENetPeer *  peer,
    enet_uint32  interval,
    enet_uint32  acceleration,
    enet_uint32  deceleration 
    )

    #include <peer.c>

    Configures throttle parameter for a peer.

    Unreliable packets are dropped by ENet in response to the varying conditions of the Internet connection to the peer. The throttle represents a probability that an unreliable packet should not be dropped and thus sent by ENet to the peer. The lowest mean round trip time from the sending of a reliable packet to the receipt of its acknowledgement is measured over an amount of time specified by the interval parameter in milliseconds. If a measured round trip time happens to be significantly less than the mean round trip time measured over the interval, then the throttle probability is increased to allow more traffic by an amount specified in the acceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant. If a measured round trip time happens to be significantly greater than the mean round trip time measured over the interval, then the throttle probability is decreased to limit traffic by an amount specified in the deceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant. When the throttle has a value of ENET_PEER_PACKET_THROTTLE_SCALE, no unreliable packets are dropped by ENet, and so 100% of all unreliable packets will be sent. When the throttle has a value of 0, all unreliable packets are dropped by ENet, and so 0% of all unreliable packets will be sent. Intermediate values for the throttle represent intermediate probabilities between 0% and 100% of unreliable packets being sent. The bandwidth limits of the local and foreign hosts are taken into account to determine a sensible limit for the throttle probability above which it should not raise even in the best of conditions.

    Parameters
    peerpeer to configure
    intervalinterval, in milliseconds, over which to measure lowest mean RTT; the default value is ENET_PEER_PACKET_THROTTLE_INTERVAL.
    accelerationrate at which to increase the throttle probability as mean RTT declines
    decelerationrate at which to decrease the throttle probability as mean RTT increases

    ◆ enet_peer_timeout()

    void enet_peer_timeout ( ENetPeer *  peer,
    enet_uint32  timeoutLimit,
    enet_uint32  timeoutMinimum,
    enet_uint32  timeoutMaximum 
    )

    #include <peer.c>

    Sets the timeout parameters for a peer.

    The timeout parameter control how and when a peer will timeout from a failure to acknowledge reliable traffic. Timeout values use an exponential backoff mechanism, where if a reliable packet is not acknowledge within some multiple of the average RTT plus a variance tolerance, the timeout will be doubled until it reaches a set limit. If the timeout is thus at this limit and reliable packets have been sent but not acknowledged within a certain minimum time period, the peer will be disconnected. Alternatively, if reliable packets have been sent but not acknowledged for a certain maximum time period, the peer will be disconnected regardless of the current timeout limit value.

    Parameters
    peerthe peer to adjust
    timeoutLimitthe timeout limit; defaults to ENET_PEER_TIMEOUT_LIMIT if 0
    timeoutMinimumthe timeout minimum; defaults to ENET_PEER_TIMEOUT_MINIMUM if 0
    timeoutMaximumthe timeout maximum; defaults to ENET_PEER_TIMEOUT_MAXIMUM if 0

    Detailed Description

    ENet packet structure.

    An ENet data packet that may be sent to or received from a peer. The shown fields should only be read and never modified. The data field contains the allocated data for the packet. The dataLength fields specifies the length of the allocated data. The flags field is either 0 (specifying no flags), or a bitwise-or of any combination of the following flags:

    ENET_PACKET_FLAG_RELIABLE - packet must be received by the target peer and resend attempts should be made until the packet is delivered

    ENET_PACKET_FLAG_UNSEQUENCED - packet will not be sequenced with other packets (not supported for reliable packets)

    ENET_PACKET_FLAG_NO_ALLOCATE - packet will not allocate data, and user must supply it instead

    ENET_PACKET_FLAG_UNRELIABLE_FRAGMENT - packet will be fragmented using unreliable (instead of reliable) sends if it exceeds the MTU

    ENET_PACKET_FLAG_SENT - whether the packet has been sent from all queues it has been entered into

    Function Documentation

    ◆ enet_deinitialize()

    void enet_deinitialize ( void  )

    #include <include/enet/enet.h>

    Shuts down ENet globally.

    Should be called when a program that has initialized ENet exits.

    ◆ enet_initialize()

    int enet_initialize ( void  )

    #include <include/enet/enet.h>

    Initializes ENet globally.

    Must be called prior to using any functions in ENet.

    Returns
    0 on success, < 0 on failure

    ◆ enet_initialize_with_callbacks()

    int enet_initialize_with_callbacks ( ENetVersion  version,
    const ENetCallbacks *  inits 
    )

    #include <include/enet/enet.h>

    Initializes ENet globally and supplies user-overridden callbacks.

    Must be called prior to using any functions in ENet. Do not use enet_initialize() if you use this variant. Make sure the ENetCallbacks structure is zeroed out so that any additional callbacks added in future versions will be properly ignored.

    Parameters
    versionthe constant ENET_VERSION should be supplied so ENet knows which version of ENetCallbacks struct to use
    initsuser-overridden callbacks where any NULL callbacks will use ENet's defaults
    Returns
    0 on success, < 0 on failure

    ◆ enet_linked_version()

    ENetVersion enet_linked_version ( void  )

    #include <include/enet/enet.h>

    Gives the linked version of the ENet library.

    Returns

    ENet  v1.3.17
    Reliable UDP networking library
    Features and Architecture

    ENet evolved specifically as a UDP networking layer for the multiplayer first person shooter Cube.

    Cube necessitated low latency communication with data sent out very frequently, so TCP was an unsuitable choice due to its high latency and stream orientation. UDP, however, lacks many sometimes necessary features from TCP such as reliability, sequencing, unrestricted packet sizes, and connection management. So UDP by itself was not suitable as a network protocol either. No suitable freely available networking libraries existed at the time of ENet's creation to fill this niche.

    UDP and TCP could have been used together in Cube to benefit somewhat from both of their features, however, the resulting combinations of protocols still leaves much to be desired. TCP lacks multiple streams of communication without resorting to opening many sockets and complicates delineation of packets due to its buffering behavior. UDP lacks sequencing, connection management, management of bandwidth resources, and imposes limitations on the size of packets. A significant investment is required to integrate these two protocols, and the end result is worse off in features and performance than the uniform protocol presented by ENet.

    ENet thus attempts to address these issues and provide a single, uniform protocol layered over UDP to the developer with the best features of UDP and TCP as well as some useful features neither provide, with a much cleaner integration than any resulting from a mixture of UDP and TCP.

    Connection Management

    ENet provides a simple connection interface over which to communicate with a foreign host. The liveness of the connection is actively monitored by pinging the foreign host at frequent intervals, and also monitors the network conditions from the local host to the foreign host such as the mean round trip time and packet loss in this fashion.

    Sequencing

    Rather than a single byte stream that complicates the delineation of packets, ENet presents connections as multiple, properly sequenced packet streams that simplify the transfer of various types of data.

    ENet provides sequencing for all packets by assigning to each sent packet a sequence number that is incremented as packets are sent. ENet guarantees that no packet with a higher sequence number will be delivered before a packet with a lower sequence number, thus ensuring packets are delivered exactly in the order they are sent.

    For unreliable packets, ENet will simply discard the lower sequence number packet if a packet with a higher sequence number has already been delivered. This allows the packets to be dispatched immediately as they arrive, and reduce latency of unreliable packets to an absolute minimum. For reliable packets, if a higher sequence number packet arrives, but the preceding packets in the sequence have not yet arrived, ENet will stall delivery of the higher sequence number packets until its predecessors have arrived.

    Channels

    Since ENet will stall delivery of reliable packets to ensure proper sequencing, and consequently any packets of higher sequence number whether reliable or unreliable, in the event the reliable packet's predecessors have not yet arrived, this can introduce latency into the delivery of other packets which may not need to be as strictly ordered with respect to the packet that stalled their delivery.

    To combat this latency and reduce the ordering restrictions on packets, ENet provides multiple channels of communication over a given connection. Each channel is independently sequenced, and so the delivery status of a packet in one channel will not stall the delivery of other packets in another channel.

    Reliability

    ENet provides optional reliability of packet delivery by ensuring the foreign host acknowledges receipt of all reliable packets. ENet will attempt to resend the packet up to a reasonable amount of times, if no acknowledgement of the packet's receipt happens within a specified timeout. Retry timeouts are progressive and become more lenient with every failed attempt to allow for temporary turbulence in network conditions.

    Fragmentation and Reassembly

    ENet will send and deliver packets regardless of size. Large packets are fragmented into many smaller packets of suitable size, and reassembled on the foreign host to recover the original packet for delivery. The process is entirely transparent to the developer.

    Aggregation

    ENet aggregates all protocol commands, including acknowledgements and packet transfer, into larger protocol packets to ensure the proper utilization of the connection and to limit the opportunities for packet loss that might otherwise result in further delivery latency.

    Adaptability

    ENet provides an in-flight data window for reliable packets to ensure connections are not overwhelmed by volumes of packets. It also provides a static bandwidth allocation mechanism to ensure the total volume of packets sent and received to a host don't exceed the host's capabilities. Further, ENet also provides a dynamic throttle that responds to deviations from normal network connections to rectify various types of network congestion by further limiting the volume of packets sent.

    Portability

    ENet works on Windows and any other Unix or Unix-like platform providing a BSD sockets interface. The library has a small and stable code base that can easily be extended to support other platforms and integrates easily. ENet makes no assumptions about the underlying platform's endianess or word size.

    Freedom

    ENet demands no royalties and doesn't carry a viral license that would restrict you in how you might use it in your programs. ENet is licensed under a short-and-sweet MIT-style license, which gives you the freedom to do anything you want with it (well, almost anything).

    Connecting to an ENet host

    Initialization

    You should include the file <enet/enet.h> when using ENet. Do not include <enet.h> without the directory prefix, as this may cause file name conflicts on some systems.

    Before using ENet, you must call enet_initialize() to initialize the library. Upon program exit, you should call enet_deinitialize() so that the library may clean up any used resources.

    #include <enet/enet.h>
    int
    main (int argc, char ** argv)
    {
    if (enet_initialize () != 0)
    {
    fprintf (stderr, "An error occurred while initializing ENet.\n");
    return EXIT_FAILURE;
    }
    atexit (enet_deinitialize);
    ...
    ...
    ...
    }

    Creating an ENet server

    Servers in ENet are constructed with enet_host_create(). You must specify an address on which to receive data and new connections, as well as the maximum allowable numbers of connected peers. You may optionally specify the incoming and outgoing bandwidth of the server in bytes per second so that ENet may try to statically manage bandwidth resources among connected peers in addition to its dynamic throttling algorithm; specifying 0 for these two options will cause ENet to rely entirely upon its dynamic throttling algorithm to manage bandwidth.

    When done with a host, the host may be destroyed with enet_host_destroy(). All connected peers to the host will be reset, and the resources used by the host will be freed.

    ENetAddress address;
    ENetHost * server;
    /* Bind the server to the default localhost. */
    /* A specific host address can be specified by */
    /* enet_address_set_host (& address, "x.x.x.x"); */
    address.host = ENET_HOST_ANY;
    /* Bind the server to port 1234. */
    address.port = 1234;
    server = enet_host_create (& address /* the address to bind the server host to */,
    32 /* allow up to 32 clients and/or outgoing connections */,
    2 /* allow up to 2 channels to be used, 0 and 1 */,
    0 /* assume any amount of incoming bandwidth */,
    0 /* assume any amount of outgoing bandwidth */);
    if (server == NULL)
    {
    fprintf (stderr,
    "An error occurred while trying to create an ENet server host.\n");
    exit (EXIT_FAILURE);
    }
    ...
    ...
    ...
    enet_host_destroy(server);

    Creating an ENet client

    Clients in ENet are similarly constructed with enet_host_create() when no address is specified to bind the host to. Bandwidth may be specified for the client host as in the above example. The peer count controls the maximum number of connections to other server hosts that may be simultaneously open.

    ENetHost * client;
    client = enet_host_create (NULL /* create a client host */,
    1 /* only allow 1 outgoing connection */,
    2 /* allow up 2 channels to be used, 0 and 1 */,
    0 /* assume any amount of incoming bandwidth */,
    0 /* assume any amount of outgoing bandwidth */);
    if (client == NULL)
    {
    fprintf (stderr,
    "An error occurred while trying to create an ENet client host.\n");
    exit (EXIT_FAILURE);
    }
    ...
    ...
    ...
    enet_host_destroy(client);

    Managing an ENet host

    ENet uses a polled event model to notify the programmer of significant events. ENet hosts are polled for events with enet_host_service(), where an optional timeout value in milliseconds may be specified to control how long ENet will poll; if a timeout of 0 is specified, enet_host_service() will return immediately if there are no events to dispatch. enet_host_service() will return 1 if an event was dispatched within the specified timeout.

    Beware that most processing of the network with the ENet stack is done inside enet_host_service(). Both hosts that make up the sides of a connection must regularly call this function to ensure packets are actually sent and received. A common symptom of not actively calling enet_host_service() on both ends is that one side receives events while the other does not. The best way to schedule this activity to ensure adequate service is, for example, to call enet_host_service() with a 0 timeout (meaning non-blocking) at the beginning of every frame in a game loop.

    Currently there are only four types of significant events in ENet:

    An event of type ENET_EVENT_TYPE_NONE is returned if no event occurred within the specified time limit. enet_host_service() will return 0 with this event.

    An event of type ENET_EVENT_TYPE_CONNECT is returned when either a new client host has connected to the server host or when an attempt to establish a connection with a foreign host has succeeded. Only the "peer" field of the event structure is valid for this event and contains the newly connected peer.

    An event of type ENET_EVENT_TYPE_RECEIVE is returned when a packet is received from a connected peer. The "peer" field contains the peer the packet was received from, "channelID" is the channel on which the packet was sent, and "packet" is the packet that was sent. The packet contained in the "packet" field must be destroyed with enet_packet_destroy() when you are done inspecting its contents.

    An event of type ENET_EVENT_TYPE_DISCONNECT is returned when a connected peer has either explicitly disconnected or timed out. Only the "peer" field of the event structure is valid for this event and contains the peer that disconnected. Only the "data" field of the peer is still valid on a disconnect event and must be explicitly reset.

    ENetEvent event;
    /* Wait up to 1000 milliseconds for an event. */
    while (enet_host_service (client, & event, 1000) > 0)
    {
    switch (event.type)
    {
    case ENET_EVENT_TYPE_CONNECT:
    printf ("A new client connected from %x:%u.\n",
    event.peer -> address.host,
    event.peer -> address.port);
    /* Store any relevant client information here. */
    event.peer -> data = "Client information";
    break;
    case ENET_EVENT_TYPE_RECEIVE:
    printf ("A packet of length %u containing %s was received from %s on channel %u.\n",
    event.packet -> dataLength,
    event.packet -> data,
    event.peer -> data,
    event.channelID);
    /* Clean up the packet now that we're done using it. */
    enet_packet_destroy (event.packet);
    break;
    case ENET_EVENT_TYPE_DISCONNECT:
    printf ("%s disconnected.\n", event.peer -> data);
    /* Reset the peer's client information. */
    event.peer -> data = NULL;
    }
    }
    ...
    ...
    ...

    Sending a packet to an ENet peer

    Packets in ENet are created with enet_packet_create(), where the size of the packet must be specified. Optionally, initial data may be specified to copy into the packet.

    Certain flags may also be supplied to enet_packet_create() to control various packet features:

    ENET_PACKET_FLAG_RELIABLE specifies that the packet must use reliable delivery. A reliable packet is guaranteed to be delivered, and a number of retry attempts will be made until an acknowledgement is received from the foreign host the packet is sent to. If a certain number of retry attempts is reached without any acknowledgement, ENet will assume the peer has disconnected and forcefully reset the connection. If this flag is not specified, the packet is assumed an unreliable packet, and no retry attempts will be made nor acknowledgements generated.

    A packet may be resized (extended or truncated) with enet_packet_resize().

    A packet is sent to a foreign host with enet_peer_send(). enet_peer_send() accepts a channel id over which to send the packet to a given peer. Once the packet is handed over to ENet with enet_peer_send(), ENet will handle its deallocation and enet_packet_destroy() should not be used upon it.

    One may also use enet_host_broadcast() to send a packet to all connected peers on a given host over a specified channel id, as with enet_peer_send().

    Queued packets will be sent on a call to enet_host_service(). Alternatively, enet_host_flush() will send out queued packets without dispatching any events.

    /* Create a reliable packet of size 7 containing "packet\0" */
    ENetPacket * packet = enet_packet_create ("packet",
    strlen ("packet") + 1,
    ENET_PACKET_FLAG_RELIABLE);
    /* Extend the packet so and append the string "foo", so it now */
    /* contains "packetfoo\0" */
    enet_packet_resize (packet, strlen ("packetfoo") + 1);
    strcpy (& packet -> data [strlen ("packet")], "foo");
    /* Send the packet to the peer over channel id 0. */
    /* One could also broadcast the packet by */
    /* enet_host_broadcast (host, 0, packet); */
    enet_peer_send (peer, 0, packet);
    ...
    ...
    ...
    /* One could just use enet_host_service() instead. */
    enet_host_flush (host);

    Disconnecting an ENet peer

    Peers may be gently disconnected with enet_peer_disconnect(). A disconnect request will be sent to the foreign host, and ENet will wait for an acknowledgement from the foreign host before finally disconnecting. An event of type ENET_EVENT_TYPE_DISCONNECT will be generated once the disconnection succeeds. Normally timeouts apply to the disconnect acknowledgement, and so if no acknowledgement is received after a length of time the peer will be forcefully disconnected.

    enet_peer_reset() will forcefully disconnect a peer. The foreign host will get no notification of a disconnect and will time out on the foreign host. No event is generated.

    ENetEvent event;
    enet_peer_disconnect (peer, 0);
    /* Allow up to 3 seconds for the disconnect to succeed
    * and drop any packets received packets.
    */
    while (enet_host_service (client, & event, 3000) > 0)
    {
    switch (event.type)
    {
    case ENET_EVENT_TYPE_RECEIVE:
    enet_packet_destroy (event.packet);
    break;
    case ENET_EVENT_TYPE_DISCONNECT:
    puts ("Disconnection succeeded.");
    return;
    ...
    ...
    ...
    }
    }
    /* We've arrived here, so the disconnect attempt didn't */
    /* succeed yet. Force the connection down. */
    enet_peer_reset (peer);
    ...
    ...
    ...

    Connecting to an ENet host

    A connection to a foreign host is initiated with enet_host_connect(). It accepts the address of a foreign host to connect to, and the number of channels that should be allocated for communication. If N channels are allocated for use, their channel ids will be numbered 0 through N-1. A peer representing the connection attempt is returned, or NULL if there were no available peers over which to initiate the connection. When the connection attempt succeeds, an event of type ENET_EVENT_TYPE_CONNECT will be generated. If the connection attempt times out or otherwise fails, an event of type ENET_EVENT_TYPE_DISCONNECT will be generated.

    ENetAddress address;
    ENetEvent event;
    ENetPeer *peer;
    /* Connect to some.server.net:1234. */
    enet_address_set_host (& address, "some.server.net");
    address.port = 1234;
    /* Initiate the connection, allocating the two channels 0 and 1. */
    peer = enet_host_connect (client, & address, 2, 0);
    if (peer == NULL)
    {
    fprintf (stderr,
    "No available peers for initiating an ENet connection.\n");
    exit (EXIT_FAILURE);
    }
    /* Wait up to 5 seconds for the connection attempt to succeed. */
    if (enet_host_service (client, & event, 5000) > 0 &&
    event.type == ENET_EVENT_TYPE_CONNECT)
    {
    puts ("Connection to some.server.net:1234 succeeded.");
    ...
    ...
    ...
    }
    else
    {
    /* Either the 5 seconds are up or a disconnect event was */
    /* received. Reset the peer in the event the 5 seconds */
    /* had run out without any significant event. */
    enet_peer_reset (peer);
    puts ("Connection to some.server.net:1234 failed.");
    }
    ...
    ...

First, make sure you download the latest source distribution at @ref Downloads. @section Unix Unix-like Operating Systems If you are using an ENet release, then you should simply be able to build it by doing the following: ./configure && make && make install If you obtained the package from github, you must have automake and autoconf available to generate the build system first by doing the following command before using the above mentioned build procedure: autoreconf -vfi @subsection SolarisBSD Solaris and BSD When building ENet under Solaris, you must specify the -lsocket and -lnsl parameters to your compiler to ensure that the sockets library is linked in. @section Windows Microsoft Windows You may simply use the included "enet.lib" or "enet64.lib" static libraries. However, if you wish to build the library yourself, then the following instructions apply: There is an included MSVC 6 project (enet.dsp) which you may use to build a suitable library file. Alternatively, you may simply drag all the ENet source files into your main project. You will have to link to the Winsock2 libraries, so make sure to add ws2_32.lib and winmm.lib to your library list (Project Settings | Link | Object/library modules). @subsection enet.dsp Building with the included enet.dsp Load the included enet.dsp. MSVC may ask you to convert it if you are on a newer version of MSVC - just allow the conversion and save the resulting project as "enet" or similar. After you build this project, it will output an "enet.lib" file to either the "Debug/" or "Release/" directory, depending on which configuration you have selected to build. By default, it should produce "Debug/enet.lib". You may then copy the resulting "enet.lib" file and the header files found in the "include/" directory to your other projects and add it to their library lists. Make sure to also link against "ws2_32.lib" and "winmm.lib" as described above. @subsection DLL DLL If you wish to build ENet as a DLL you must first define ENET_DLL within the project (Project Settings | C/C++ | Preprocessor | Preprocessor definitions) or, more invasively, simply define ENET_DLL at the top of enet.h. */ enet-1.3.17/docs/design.dox0000644000175000017500000001356413754264327013575 0ustar leelee/** @page Features Features and Architecture ENet evolved specifically as a UDP networking layer for the multiplayer first person shooter Cube. Cube necessitated low latency communication with data sent out very frequently, so TCP was an unsuitable choice due to its high latency and stream orientation. UDP, however, lacks many sometimes necessary features from TCP such as reliability, sequencing, unrestricted packet sizes, and connection management. So UDP by itself was not suitable as a network protocol either. No suitable freely available networking libraries existed at the time of ENet's creation to fill this niche. UDP and TCP could have been used together in Cube to benefit somewhat from both of their features, however, the resulting combinations of protocols still leaves much to be desired. TCP lacks multiple streams of communication without resorting to opening many sockets and complicates delineation of packets due to its buffering behavior. UDP lacks sequencing, connection management, management of bandwidth resources, and imposes limitations on the size of packets. A significant investment is required to integrate these two protocols, and the end result is worse off in features and performance than the uniform protocol presented by ENet. ENet thus attempts to address these issues and provide a single, uniform protocol layered over UDP to the developer with the best features of UDP and TCP as well as some useful features neither provide, with a much cleaner integration than any resulting from a mixture of UDP and TCP. @section CM Connection Management ENet provides a simple connection interface over which to communicate with a foreign host. The liveness of the connection is actively monitored by pinging the foreign host at frequent intervals, and also monitors the network conditions from the local host to the foreign host such as the mean round trip time and packet loss in this fashion. @section Sequencing Sequencing Rather than a single byte stream that complicates the delineation of packets, ENet presents connections as multiple, properly sequenced packet streams that simplify the transfer of various types of data. ENet provides sequencing for all packets by assigning to each sent packet a sequence number that is incremented as packets are sent. ENet guarantees that no packet with a higher sequence number will be delivered before a packet with a lower sequence number, thus ensuring packets are delivered exactly in the order they are sent. For unreliable packets, ENet will simply discard the lower sequence number packet if a packet with a higher sequence number has already been delivered. This allows the packets to be dispatched immediately as they arrive, and reduce latency of unreliable packets to an absolute minimum. For reliable packets, if a higher sequence number packet arrives, but the preceding packets in the sequence have not yet arrived, ENet will stall delivery of the higher sequence number packets until its predecessors have arrived. @section Channels Channels Since ENet will stall delivery of reliable packets to ensure proper sequencing, and consequently any packets of higher sequence number whether reliable or unreliable, in the event the reliable packet's predecessors have not yet arrived, this can introduce latency into the delivery of other packets which may not need to be as strictly ordered with respect to the packet that stalled their delivery. To combat this latency and reduce the ordering restrictions on packets, ENet provides multiple channels of communication over a given connection. Each channel is independently sequenced, and so the delivery status of a packet in one channel will not stall the delivery of other packets in another channel. @section Reliability Reliability ENet provides optional reliability of packet delivery by ensuring the foreign host acknowledges receipt of all reliable packets. ENet will attempt to resend the packet up to a reasonable amount of times, if no acknowledgement of the packet's receipt happens within a specified timeout. Retry timeouts are progressive and become more lenient with every failed attempt to allow for temporary turbulence in network conditions. @section FaR Fragmentation and Reassembly ENet will send and deliver packets regardless of size. Large packets are fragmented into many smaller packets of suitable size, and reassembled on the foreign host to recover the original packet for delivery. The process is entirely transparent to the developer. @section Aggregation Aggregation ENet aggregates all protocol commands, including acknowledgements and packet transfer, into larger protocol packets to ensure the proper utilization of the connection and to limit the opportunities for packet loss that might otherwise result in further delivery latency. @section Adaptability Adaptability ENet provides an in-flight data window for reliable packets to ensure connections are not overwhelmed by volumes of packets. It also provides a static bandwidth allocation mechanism to ensure the total volume of packets sent and received to a host don't exceed the host's capabilities. Further, ENet also provides a dynamic throttle that responds to deviations from normal network connections to rectify various types of network congestion by further limiting the volume of packets sent. @section Portability Portability ENet works on Windows and any other Unix or Unix-like platform providing a BSD sockets interface. The library has a small and stable code base that can easily be extended to support other platforms and integrates easily. ENet makes no assumptions about the underlying platform's endianess or word size. @section Freedom Freedom ENet demands no royalties and doesn't carry a viral license that would restrict you in how you might use it in your programs. ENet is licensed under a short-and-sweet MIT-style license, which gives you the freedom to do anything you want with it (well, almost anything). */ enet-1.3.17/docs/license.dox0000644000175000017500000000210613754264327013734 0ustar leelee/** @page License License Copyright (c) 2002-2020 Lee Salzman Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Unreliable packets are dropped by ENet in response to the varying conditions of the Internet connection to the peer. The throttle represents a probability that an unreliable packet should not be dropped and thus sent by ENet to the peer. The lowest mean round trip time from the sending of a reliable packet to the receipt of its acknowledgement is measured over an amount of time specified by the interval parameter in milliseconds. If a measured round trip time happens to be significantly less than the mean round trip time measured over the interval, then the throttle probability is increased to allow more traffic by an amount specified in the acceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant. If a measured round trip time happens to be significantly greater than the mean round trip time measured over the interval, then the throttle probability is decreased to limit traffic by an amount specified in the deceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant. When the throttle has a value of ENET_PEER_PACKET_THROTTLE_SCALE, no unreliable packets are dropped by ENet, and so 100% of all unreliable packets will be sent.

The enet_host_connect and enet_host_create API functions require supplying additional parameters. ENet 1.2.5 (June 28, 2011): * fixed bug with simultaneous disconnects not dispatching events ENet 1.2.4 (May 31, 2011): * fixed regression in unreliable packet queuing * added check against received port to limit some forms of IP-spoofing ENet 1.2.3 (February 10, 2011): * fixed bug in tracking reliable data in transit ENet 1.2.2 (June 5, 2010): * checksum functionality is now enabled by setting a checksum callback inside ENetHost instead of being a configure script option * added totalSentData, totalSentPackets, totalReceivedData, and totalReceivedPackets counters inside ENetHost for getting usage statistics * added enet_host_channel_limit() for limiting the maximum number of channels allowed by connected peers * now uses dispatch queues for event dispatch rather than potentially unscalable array walking * added no_memory callback that is called when a malloc attempt fails, such that if no_memory returns rather than aborts (the default behavior), then the error is propagated to the return value of the API calls * now uses packed attribute for protocol structures on platforms with strange alignment rules * improved autoconf build system contributed by Nathan Brink allowing for easier building as a shared library Caveats: If you were using the compile-time option that enabled checksums, make sure to set the checksum callback inside ENetHost to enet_crc32 to regain the old behavior. The ENetCallbacks structure has added new fields, so make sure to clear the structure to zero before use if using enet_initialize_with_callbacks(). ENet 1.2.1 (November 12, 2009): * fixed bug that could cause disconnect events to be dropped * added thin wrapper around select() for portable usage * added ENET_SOCKOPT_REUSEADDR socket option * factored enet_socket_bind()/enet_socket_listen() out of enet_socket_create() * added contributed Code::Blocks build file ENet 1.2 (February 12, 2008): * fixed bug in VERIFY_CONNECT acknowledgement that could cause connect attempts to occasionally timeout * fixed acknowledgements to check both the outgoing and sent queues when removing acknowledged packets * fixed accidental bit rot in the MSVC project file * revised sequence number overflow handling to address some possible disconnect bugs * added enet_host_check_events() for getting only local queued events * factored out socket option setting into enet_socket_set_option() so that socket options are now set separately from enet_socket_create() Caveats: While this release is superficially protocol compatible with 1.1, differences in the sequence number overflow handling can potentially cause random disconnects. ENet 1.1 (June 6, 2007): * optional CRC32 just in case someone needs a stronger checksum than UDP provides (--enable-crc32 configure option) * the size of packet headers are half the size they used to be (so less overhead when sending small packets) * enet_peer_disconnect_later() that waits till all queued outgoing packets get sent before issuing an actual disconnect * freeCallback field in individual packets for notification of when a packet is about to be freed * ENET_PACKET_FLAG_NO_ALLOCATE for supplying pre-allocated data to a packet (can be used in concert with freeCallback to support some custom allocation schemes that the normal memory allocation callbacks would normally not allow) * enet_address_get_host_ip() for printing address numbers * promoted the enet_socket_*() functions to be part of the API now * a few stability/crash fixes enet-1.3.17/Makefile.am0000644000175000017500000000123013754264327012677 0ustar leeleepkgconfigdir = $(libdir)/pkgconfig nodist_pkgconfig_DATA = libenet.pc enetincludedir=$(includedir)/enet enetinclude_HEADERS = \ include/enet/callbacks.h \ include/enet/enet.h \ include/enet/list.h \ include/enet/protocol.h \ include/enet/time.h \ include/enet/types.h \ include/enet/unix.h \ include/enet/utility.h \ include/enet/win32.h lib_LTLIBRARIES = libenet.la libenet_la_SOURCES = callbacks.c compress.c host.c list.c packet.c peer.c protocol.c unix.c win32.c # see info '(libtool) Updating version info' before making a release libenet_la_LDFLAGS = $(AM_LDFLAGS) -version-info 7:5:0 AM_CPPFLAGS = -I$(top_srcdir)/include ACLOCAL_AMFLAGS = -Im4 enet-1.3.17/enet.dsp0000644000175000017500000000770713754264327012325 0ustar leelee# Microsoft Developer Studio Project File - Name="enet" - Package Owner=<4> # Microsoft Developer Studio Generated Build File, Format Version 6.00 # ** DO NOT EDIT ** # TARGTYPE "Win32 (x86) Static Library" 0x0104 CFG=enet - Win32 Debug !MESSAGE This is not a valid makefile.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'. Add to this or # override it after sourcing this library to reflect the full set of # options your script accepts. usage_message="\ --debug enable verbose shell tracing -W, --warnings=CATEGORY report the warnings falling in CATEGORY [all] -v, --verbose verbosely report processing --version print version information and exit -h, --help print short or long help message and exit " # Additional text appended to 'usage_message' in response to '--help'. long_help_message=" Warning categories include: 'all' show all warnings 'none' turn off all the warnings 'error' warnings are treated as fatal errors" # Help message printed before fatal option parsing errors. fatal_help="Try '\$progname --help' for more information." ## ------------------------- ## ## Hook function management. ## ## ------------------------- ## # This section contains functions for adding, removing, and running hooks # to the main code.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

AUTOLINK_SUPPORT = YES # If you use STL classes (i.e. std::string, std::vector, etc.) but do not want # to include (a tag file for) the STL sources as input, then you should set this # tag to YES in order to let doxygen match functions declarations and # definitions whose arguments contain STL classes (e.g. func(std::string); # versus func(std::string) {}).

Since the tabs in the index contain the same information as the navigation # tree, you can set this option to YES if you also set GENERATE_TREEVIEW to YES. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES. DISABLE_INDEX = NO # The GENERATE_TREEVIEW tag is used to specify whether a tree-like index # structure should be generated to display hierarchical information. If the tag # value is set to YES, a side panel will be generated containing a tree-like # index structure (just like the one that is generated for HTML Help). For this # to work a browser that supports JavaScript, DHTML, CSS and frames is required # (i.e. any modern browser). Windows users are probably better off using the # HTML help feature. Via custom stylesheets (see HTML_EXTRA_STYLESHEET) one can # further fine-tune the look of the index. As an example, the default style # sheet generated by doxygen has an example that shows how to put an image at # the root of the tree instead of the PROJECT_NAME. Since the tree basically has # the same information as the tab index, you could consider setting # DISABLE_INDEX to YES when enabling this option. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES. GENERATE_TREEVIEW = NO # The ENUM_VALUES_PER_LINE tag can be used to set the number of enum values that # doxygen will group on one line in the generated HTML documentation. # # Note that a value of 0 will completely suppress the enum values from appearing # in the overview section. # Minimum value: 0, maximum value: 20, default value: 4. # This tag requires that the tag GENERATE_HTML is set to YES. ENUM_VALUES_PER_LINE = 1 # If the treeview is enabled (see GENERATE_TREEVIEW) then this tag can be used # to set the initial width (in pixels) of the frame in which the tree is shown. # Minimum value: 0, maximum value: 1500, default value: 250. # This tag requires that the tag GENERATE_HTML is set to YES. TREEVIEW_WIDTH = 250 # When the EXT_LINKS_IN_WINDOW option is set to YES doxygen will open links to # external symbols imported via tag files in a separate window. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES. EXT_LINKS_IN_WINDOW = NO # Use this tag to change the font size of LaTeX formulas included as images in # the HTML documentation. When you change the font size after a successful # doxygen run you need to manually remove any form_*.png images from the HTML # output directory to force them to be regenerated. # Minimum value: 8, maximum value: 50, default value: 10. # This tag requires that the tag GENERATE_HTML is set to YES. FORMULA_FONTSIZE = 10 # Use the FORMULA_TRANPARENT tag to determine whether or not the images # generated for formulas are transparent PNGs. Transparent PNGs are not # supported properly for IE 6.0, but are supported on all modern browsers. # # Note that when changing this option you need to delete any form_*.png files in # the HTML output directory before the changes have effect. # The default value is: YES. # This tag requires that the tag GENERATE_HTML is set to YES. FORMULA_TRANSPARENT = YES # Enable the USE_MATHJAX option to render LaTeX formulas using MathJax (see # http://www.mathjax.org) which uses client side Javascript for the rendering # instead of using prerendered bitmaps. Use this if you do not have LaTeX # installed or if you want to formulas look prettier in the HTML output. When # enabled you may also need to install MathJax separately and configure the path # to it using the MATHJAX_RELPATH option. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES. USE_MATHJAX = NO # When MathJax is enabled you can set the default output format to be used for # the MathJax output. See the MathJax site (see: # http://docs.mathjax.org/en/latest/output.html) for more details. # Possible values are: HTML-CSS (which is slower, but has the best # compatibility), NativeMML (i.e. MathML) and SVG. # The default value is: HTML-CSS. # This tag requires that the tag USE_MATHJAX is set to YES. MATHJAX_FORMAT = HTML-CSS # When MathJax is enabled you need to specify the location relative to the HTML # output directory using the MATHJAX_RELPATH option. The destination directory # should contain the MathJax.js script. For instance, if the mathjax directory # is located at the same level as the HTML output directory, then # MATHJAX_RELPATH should be ../mathjax. The default value points to the MathJax # Content Delivery Network so you can quickly see the result without installing # MathJax. However, it is strongly recommended to install a local copy of # MathJax from http://www.mathjax.org before deployment. # The default value is: http://cdn.mathjax.org/mathjax/latest. # This tag requires that the tag USE_MATHJAX is set to YES. MATHJAX_RELPATH = http://cdn.mathjax.org/mathjax/latest # The MATHJAX_EXTENSIONS tag can be used to specify one or more MathJax # extension names that should be enabled during MathJax rendering.

MATHJAX_EXTENSIONS = # The MATHJAX_CODEFILE tag can be used to specify a file with javascript pieces # of code that will be used on startup of the MathJax code.
