Function Documentation

static int inet_pton4	(	const char *	src,
		unsigned char *	dst
	)			[static]

like inet_aton() but without all the hexadecimal and shorthand.

Returns:

1 if `src' is a valid dotted quad, else 0.

Note:

does not touch `dst' unless it's returning 1.

static int inet_pton6	(	const char *	src,
		unsigned char *	dst
	)			[static]

convert presentation level address to network order binary form.

Returns:

1 if `src' is a valid [RFC1884 2.2] address, else 0.

Note:

(1) does not touch `dst' unless it's returning 1.

(2) :: in a full address is silently ignored.

int isc_net_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).

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)
