Function Documentation

◆ enet_peer_disconnect()

void enet_peer_disconnect	(	ENetPeer *	peer,
		enet_uint32	data
	)

#include <peer.c>

Request a disconnection from a peer.

Parameters

peer	peer to request a disconnection
data	data describing the disconnection

Remarks: An ENET_EVENT_DISCONNECT event will be generated by enet_host_service() once the disconnection is complete.

◆ enet_peer_disconnect_later()

void enet_peer_disconnect_later	(	ENetPeer *	peer,
		enet_uint32	data
	)

#include <peer.c>

Request a disconnection from a peer, but only after all queued outgoing packets are sent.

Parameters

peer	peer to request a disconnection
data	data describing the disconnection

Remarks: An ENET_EVENT_DISCONNECT event will be generated by enet_host_service() once the disconnection is complete.

◆ enet_peer_disconnect_now()

void enet_peer_disconnect_now	(	ENetPeer *	peer,
		enet_uint32	data
	)

#include <peer.c>

Force an immediate disconnection from a peer.

Parameters

peer	peer to disconnect
data	data describing the disconnection

Remarks: No ENET_EVENT_DISCONNECT event will be generated. The foreign peer is not guaranteed to receive the disconnect notification, and is reset immediately upon return from this function.

◆ enet_peer_dispatch_incoming_reliable_commands()

void enet_peer_dispatch_incoming_reliable_commands	(	ENetPeer *	peer,
		ENetChannel *	channel,
		ENetIncomingCommand *	queuedCommand
	)

#include <peer.c>

◆ enet_peer_dispatch_incoming_unreliable_commands()

void enet_peer_dispatch_incoming_unreliable_commands	(	ENetPeer *	peer,
		ENetChannel *	channel,
		ENetIncomingCommand *	queuedCommand
	)

#include <peer.c>

◆ enet_peer_on_connect()

void enet_peer_on_connect ( ENetPeer * peer )

#include <peer.c>

◆ enet_peer_on_disconnect()

void enet_peer_on_disconnect ( ENetPeer * peer )

#include <peer.c>

◆ enet_peer_ping()

void enet_peer_ping ( ENetPeer * peer )

#include <peer.c>

Sends a ping request to a peer.

Parameters

peer	destination for the ping request

Remarks: ping requests factor into the mean round trip time as designated by the roundTripTime field in the ENetPeer structure. ENet automatically pings all connected peers at regular intervals, however, this function may be called to ensure more frequent ping requests.

◆ enet_peer_ping_interval()

void enet_peer_ping_interval	(	ENetPeer *	peer,
		enet_uint32	pingInterval
	)

#include <peer.c>

Sets the interval at which pings will be sent to a peer.

Pings are used both to monitor the liveness of the connection and also to dynamically adjust the throttle during periods of low traffic so that the throttle has reasonable responsiveness during traffic spikes.

Parameters

peer	the peer to adjust
pingInterval	the interval at which to send pings; defaults to ENET_PEER_PING_INTERVAL if 0

◆ enet_peer_queue_acknowledgement()

◆ enet_peer_receive()

ENetPacket* enet_peer_receive	(	ENetPeer *	peer,
		enet_uint8 *	channelID
	)

#include <peer.c>

Attempts to dequeue any incoming queued packet.

Parameters

peer	peer to dequeue packets from
channelID	holds the channel ID of the channel the packet was received on success

Returns: a pointer to the packet, or NULL if there are no available incoming queued packets

◆ enet_peer_reset()

void enet_peer_reset ( ENetPeer * peer )

#include <peer.c>

Forcefully disconnects a peer.

Parameters

peer	peer to forcefully disconnect

Remarks: The foreign host represented by the peer is not notified of the disconnection and will timeout on its connection to the local host.

void enet_peer_reset_queues ( ENetPeer * peer )

#include <peer.c>

◆ enet_peer_send()

int enet_peer_send	(	ENetPeer *	peer,

◆ 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

peer	peer to configure
interval	interval, in milliseconds, over which to measure lowest mean RTT; the default value is ENET_PEER_PACKET_THROTTLE_INTERVAL.
acceleration	rate at which to increase the throttle probability as mean RTT declines
deceleration	rate 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

peer	the peer to adjust
timeoutLimit	the timeout limit; defaults to ENET_PEER_TIMEOUT_LIMIT if 0
timeoutMinimum	the timeout minimum; defaults to ENET_PEER_TIMEOUT_MINIMUM if 0
timeoutMaximum	the timeout maximum; defaults to ENET_PEER_TIMEOUT_MAXIMUM if 0
