Function Documentation

ssize_t ksnTRUDPrecvfrom	(	trudpData *	td,
		int	fd,
		void *	buffer,
		size_t	buffer_len,
		int	flags,
		__SOCKADDR_ARG	addr,
		socklen_t *	addr_len
	)

Get data from peer through TR-UDP transport.

Parameters

td
fd
buffer
buffer_len
flags
addr
addr_len

Returns

If return 0 than the packet is processed by tu->process_packet function. In other case there is value returned by UDP recvfrom function and the buffer contain received data

ssize_t ksnTRUDPsendto	(	trudpData *	td,
		int	resend_flg,
		uint32_t	id,
		int	attempt,
		int	cmd,
		int	fd,
		const void *	buf,
		size_t	buf_len,
		int	flags,
		__CONST_SOCKADDR_ARG	addr,
		socklen_t	addr_len
	)

Send to peer through TR-UDP transport.

Parameters

td	Pointer to trudpData object
resend_flg	New message or resend sent before (0 - new, 1 -resend)
id	ID of resend message
cmd	Command to allow TR-UDP
attempt	Number of attempt of this message
fd	File descriptor of UDP connection
buf	Buffer with data
buf_len	Data length
flags	Flags (always 0, reserved)
addr	Peer address
addr_len	Peer address length

Returns

Number of bytes sent to UDP

void trudp_event_cb	(	void *	tcd_pointer,
		int	event,
		void *	data,
		size_t	data_length,
		void *	user_data
	)

Parameters

tcd_pointer
event
data
data_length
user_data
