Function Documentation

bitstringtoip6()

int bitstringtoip6	(	stralloc *	ip6string,
		stralloc *	ip6addr
	)

This function converts a bit string which is produced by ip6tobitstring() into an IPv6 address. The string may start with a '^'.

Parameters

ip6string	Source string which need to be converted.
ip6addr	Destination string.

Returns

-1: No memory could allocated,0: Failure,1: Success.

Definition at line 76 of file ip6_bit.c.

Here is the call graph for this function:

ip6_compactaddr()

unsigned int ip6_compactaddr	(	char *	s,
		char	ip[16]
	)

This function converts a IPv6 address as 16 bytes char array into a compactified string.

Author

Felix von Leitner

Parameters

s	Destination address.
ip	Source address as 16 bytes char array.

Returns

0: failure, else: the number of characters of the return value.

Definition at line 15 of file ip6_compactaddr.c.

Here is the caller graph for this function:

ip6_expandaddr()

unsigned int ip6_expandaddr	(	char *	src,
		stralloc *	destination
	)

This function expands any valid IPv6 address into its full format of 16 bytes. It returns the number of processed tokens on success.

Parameters

src	Source IPv6 address.
destination	Expanded IPv6 address.

Returns

-1: No memory could allocated, 0:failure, 1: success

Definition at line 15 of file ip6_expandaddr.c.

Here is the call graph for this function:

ip6_scan()

unsigned int ip6_scan	(	const char *	src,
		char *	ip
	)

Here is the caller graph for this function:

ip6tobitstring()

int ip6tobitstring	(	char *	ip6address,
		stralloc *	ip6string,
		unsigned int	prefix
	)

This function converts a IPv6 address into its binary representation.

Parameters

ip6address	The source address.
ip6string	The destination address.
prefix	The net prefix bits (maximum 128 bits for IPv6).

Returns

-1:lack of memory,0: non valid IPv6 address,1: successful converted.
