uint32_t htonl

(

uint32_t

hostlong

)

Convert a host byte order (little-endian) long, hostlong, by returning a network byte order (big-endian) long.

uint16_t htons

(

uint16_t

hostshort

)

Convert a host byte order (little-endian) short, hostshort, by returning a network byte order (big-endian) short.

const char* inet_ntop	(	int16_t	af,
		const in6_addr_t *	src,
		char *	dst,
		uint8_t	cnt
	)

This system call converts a network address structure defined in src to the character string dst using af address family.

Precondition:

dst is a buffer large enough for the family address

Postcondition:

dst contains the string corresponding to the address in src

Parameters:

[in]	af	AF address family. See AFEnums.
[in]	src	contains an IP address string
[out]	dst	string buffer
[in]	cnt	number of bytes in the buffer

Returns:

dst if succeed or NULL if fail and errno is set appropriately

• EINVAL if invalid parameters are passed

int16_t inet_pton	(	int16_t	af,
		const char *	src,
		in6_addr_t *	dst
	)

This system call converts the character string src into a network address structure in the af address family, then copies the network address structure to dst.

Precondition:

src is a null terminated string.

Postcondition:

dst contains the correct network address corresponds to the src

Parameters:

[in]	af	AF address family. See AFEnums.
[in]	src	contains an IP address string
[out]	dst	copy into this network data structure

Returns:

0 if succeed or -1 if fail and errno is set appropriately

• EINVAL if invalid parameters are passed

uint32_t ntohl

(

uint32_t

netlong

)

Convert a network byte order (big-endian) long, netlong, by returning a host byte order (little-endian) long.

uint16_t ntohs

(

uint16_t

netshort

)

Convert a network byte order (big-endian) short, netshort, by returning a host byte order (little-endian) short.
