Function Documentation

bitstring_ip4()

int bitstring_ip4	(	stralloc *	ip4addr,
		stralloc *	ip4string
	)

/fn bitstring_ip4 /brief This function takes an IPv4 bitstring and translates it to an IPv4 address + prefix /param in: ip4string The source address (with '_' start token). /param out: ip4addr 0-terminated estination IPv4 address + net prefix (eg. 127.0.0.0/16). /return -1: lack of memory; 1: non valid IPv4 address; 0: successful converted.

bitstring_ip6()

int bitstring_ip6	(	stralloc *	ip6addr,
		stralloc *	ip6string
	)

/fn bitstring_ip6 /brief This function converts a bit string which is produced by ip6_bitstring() into an IPv6 address. The string may start with a '^'. /param in: ip6string Source string which need to be converted. /param out ip6addr 0-terminated IPv6 destination address with net prefix. /return -1: No memory could allocated,0: Failure,1: Success.

/fn ip4_bitstring /brief This function converts a IPv4 address into its binary representation with given prefix len /param out: ip4string 0-terminated destination address. /param in: ip4address The source address. /param in: prefix The net prefix bits (maximum 32 bits for IPv4). /return -1: lack of memory; 1: non valid IP address; 0: successful converted.
