Function Documentation

udp_check_free_space()

int WEAK udp_check_free_space	(	struct udp_periph *	p,
		long *	fd,
		uint16_t	len
	)

Check if there is enough free space in the transmit buffer.

Parameters

p	pointer to UDP peripheral
len	how many bytes of free space to check for

Returns

number of bytes available or 0 if not enough
