ip6(3ast)

NAME

ip6 - IPv6 address support

SYNOPSIS

#include <ip6.h>
char*      fmtip6(unsigned char* addr, int bits);
int        strtoip6(const char* str, char** end, unsigned char* addr, unsigned char* bits);

DESCRIPTION

fmtip6() formats the IPv6 address addr with optional prefix bits bits (0 if not a prefix) into a thread-specific 0-terminated temporary buffer and returns a pointer to the formatted value.

strtoip6() converts a formatted IPv6 address from the 0-terminated string str into a host order IPv6 address in addr which must be a buffer of at least IP6ADDR bytes. If bits is not 0 then an optional /bits (prefix size in bits) is parsed and *bits is set to the number of prefix bits. If end is not 0 then *end will point to the first unparsed character in str on return. 0 is returned on success, -1 on failure.
