int tsend_dgram	(	int	fd,
		char *	buf,
		unsigned int	len,
		const struct sockaddr *	to,
		socklen_t	tolen,
		int	timeout
	)

sends on dgram fd (which must be O_NONBLOCK); if it cannot send any data in timeout milliseconds it will return ERROR

Returns:

-1 on error, or number of bytes written (if less than len => couldn't send all) bugs: signals will reset the timer

int tsend_dgram_ev	(	int	fd,
		const struct iovec *	v,
		int	count,
		int	timeout
	)

sends on connected datagram fd (which must be O_NONBLOCK); if it cannot send any data in timeout milliseconds it will return ERROR

Returns:

-1 on error, or number of bytes written (if less than len => couldn't send all) bugs: signals will reset the timer

int tsend_stream	(	int	fd,
		char *	buf,
		unsigned int	len,

	)

sends on fd (which must be O_NONBLOCK); if it cannot send any data in timeout milliseconds it will return ERROR

Returns:

-1 on error, or number of bytes written (if less than len => couldn't send all) bugs: signals will reset the timer
