Returns 0 on success and -1 on -failure. - -int enet_address_get_host (const ENetAddress * address, char * hostName, size_t nameLength); - - Attempts to do a reverse lookup of the host field in the address parameter. -If successful, the name of the host is placed in the string described by -hostName and nameLength. The host name is always null-delimited and will -not exceed nameLength in length. Returns 0 on success and -1 on failure. - -ENetPacket * enet_packet_create (const void * dataContents, size_t dataLength, enet_uint32 flags); - - Creates a packet that may be sent to a peer. The dataContents parameter -specifies the initial contents of the packet's data; the packet's data will -remain uninitialized if dataContents is NULL. The dataLength parameter specifies -the size of the data that is allocated for this packet.

Returns 0 on success and -1 on failure. - -ENetHost * enet_host_create (const ENetAddress * address, size_t peerCount, enet_uint32 incomingBandwidth, enet_uint32 outgoingBandwidth); - - Creates a host for communicating with peers. The address parameter specifies -the address at which other peers may connect to this host; if the address parameter -is NULL, then no peers may connect to the host. The peerCount parameter specifies -the numbers of peers that should be allocated for the host; this limits the maximum -number of peers that may connect to this host to peerCount. The incomingBandwidth -parameter specifies the downstream bandwidth of the host in bytes per second; if -the incomingBandwidth parameter is 0, ENet will assume the host has unlimited -downstream bandwidth. The outgoingBandwidth parameter specifies the upstream bandwidth -of the host in bytes per second; if the outgoingBandwidth parameter is 0, ENet will -assume the host has unlimited upstream bandwidth. 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. -Returns the host on success and NULL on failure. - -void enet_host_destroy (ENetHost * host); - - Destroys the host and all resources associated with it. - -ENetPeer * enet_host_connect (ENetHost * host, const ENetAddress * address, size_t channelCount); - - Initiates a connection from the host specified in the host parameter to a foreign -host whose internet address is specified by the address parameter. The channelCount -parameter specifies the number of channels that should be allocated for communicating -with the foreign host. Returns a peer representing the foreign host on success and NULL -on failure. The peer returned will have not completed the connection until enet_host_service -notifies of an ENET_EVENT_TYPE_CONNECT event for the peer. - -int enet_host_service (ENetHost * host, ENetEvent * event, enet_uint32 timeout); - - Waits for events on the host specified by the host parameters and shuttles packets -between the host and its peers. The event parameter specifies an event structure -where event details will be placed if one occurs. The timeout field specifies an -amount of time in milliseconds that ENet should wait for events. Returns 1 if an -event occured within the specified time limit, 0 if no event occurred within the -time limit, and -1 on failure. This function must be called frequently for adequate -performance. - -void enet_host_flush (ENetHost * host); - - Sends out any queued packets on the host specified in the host parameters to -the designated peers. This function need only be used in circumstances where one -wishes to send queued packets earlier than in a call to enet_host_service. - -void enet_host_broadcast (ENetHost * host, enet_uint8 channelID, ENetPacket * packet); - - Queues a packet to be sent to all peers on the host specified in the host parameter -over the channel number identified by the channelID parameter. - -void enet_host_bandwidth_limit (ENetHost * host, enet_uint32 incomingBandwidth, enet_uint32 outgoingBandwidth); - - Adjusts the bandwidth limits of the host specified in the host parameter. The -incomingBandwidth and outgoingBandwidth parameters are as specified in a call to -enet_host_create. - -int enet_peer_send (ENetPeer * peer, enet_uint8 channelID, ENetPacket * packet); - - Queues a packet to be sent to the peer specified by the peer parameter over the -channel number identified by the channelID parameter. Returns 0 on success and -1 -on failure. - -ENetPacket * enet_peer_receive (ENetPeer * peer, enet_uint8 channelID); - - Attempts to dequeue any incoming queued packets on the peer specified by the peer -parameter on the channel number identified by the channelID parameter. Returns a packet -if one is available and NULL if there are no available incoming queued packets. - -void enet_peer_ping (ENetPeer * peer); - - Sends a ping request to the peer specified by the peer parameter. Ping requests factor -into the mean round trip time as designated by the roundTripTime field in the ENetPeer -structure. ENet automatically pings all connected peer at an interval, however, this -function may be called to ensure more frequent ping requests. - -void enet_peer_reset (ENetPeer * peer); - - Forcefully disconnects the peer specified by the peer parameter. The foreign host -represented by the peer is not notified of the disconnection and so will timeout on its -connection to the local host. - -void enet_peer_disconnect (ENetPeer * peer); - - Request a disconnection from the peer specified by the peer parameter. An -ENET_EVENT_DISCONNECT event will be generated by enet_host_service once the -disconnection is complete. - -void enet_peer_throttle_configure (ENetPeer * peer, enet_uint32 interval, enet_uint32 acceleration, enet_uint32 deceleration); - - Configures throttle parameter for the peer specified by the peer parameter. -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; the constant ENET_PEER_PACKET_THROTTLE_INTERVAL -is the default value for this parameter. If a measured round trip time happens -to be signifigantly 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 in ratio to the -ENET_PEER_PACKET_THROTTLE_SCALE constant. If a measured round trip time happens -to be signifigantly 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 in 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 host 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. - - - |
