Function Documentation

inet_ntop()

const char* inet_ntop	(	int	af,
		const void *	src,
		char *	dst,
		size_t	size
	)

Convert a network format address to presentation format.

Parameters

[in]	af	Address family, can be either AF_INET (IPv4) or AF_INET6 (IPv6)
[in]	src	Network address structure, can be either in_addr (IPv4) or in6_addr (IPv6)
[out]	dst	Network address string representation
[in]	size	'dst' Maximum size

Returns

pointer to presentation format address ('dst'), or NULL (see errno).

inet_pton()

int inet_pton	(	int	af,
		const char *	src,
		void *	dst
	)

Convert from presentation format (which usually means ASCII printable) to network format (which is usually some kind of binary format).

Parameters

[in]	af	Address family, can be either AF_INET (IPv4) or AF_INET6 (IPv6)
[in]	src	Network address string representation
[out]	dst	Network address structure result, can be either in_addr (IPv4) or in6_addr (IPv6)

Returns

1 if the address was valid for the specified address family; 0 if the address wasn't valid ('dst' is untouched in this case); -1 if some other error occurred ('dst' is untouched in this case, too)
