Function Documentation

uint16_t ip_checksum	(	void *	start,
		unsigned int	count,
		uint32_t	initial_value
	)

Calculates a IP checksum (as needed by IP, TCP and UDP). Parameters are start points to the beginning of the data to be checksummed count Indicates how many bytes should be checksummed Since protcols like IP and UDP work with so called Pseudo Headers (see RFC for details) you can precalculate that part and give it as initial_value to this function
