u16_t	inet_chksum_pseudo (struct pbuf *p, struct ip_addr *src, struct ip_addr *dest, u8_t proto, u32_t proto_len)
u16_t	inet_chksum (void *dataptr, u16_t len)
u16_t	inet_chksum_pbuf (struct pbuf *p)
	Calculate a checksum over a chain of pbufs (without pseudo-header, much like inet_chksum only pbufs are used).

Function Documentation

u16_t inet_chksum	(	void *	dataptr,
		u16_t	len
	)

u16_t inet_chksum_pbuf

(

struct pbuf *

p

)

Calculate a checksum over a chain of pbufs (without pseudo-header, much like inet_chksum only pbufs are used).

Parameters:

p

pbuf chain over that the checksum should be calculated

Returns:

checksum (as u16_t) to be saved directly in the protocol header
