NAME
ipsec anyaddr - get "any" address
ipsec isanyaddr - test address for equality to "any" address
ipsec unspecaddr - get "unspecified" address
ipsec isunspecaddr - test address for equality to "unspecified" address
ipsec loopbackaddr - get loopback address
ipsec isloopbackaddr - test address for equality to loopback address
SYNOPSIS
#include <freeswan.h>
const char *anyaddr(int af, ip_address *dst);
int isanyaddr(const ip_address *src);
const char *unspecaddr(int af, ip_address *dst);
int isunspecaddr(const ip_address *src);
const char *loopbackaddr(int af, ip_address *dst);
int isloopbackaddr(const ip_address *src);
DESCRIPTION
These functions fill in, and test for, special values of the
ip_address
type.
Anyaddr
fills in the destination
*dst
with the ``any'' address of address family
af
(normally
AF_INET
or
AF_INET6).
The IPv4 ``any'' address is the one embodied in the old
INADDR_ANY
macro.
Isanyaddr
returns
1
if the
src
address equals the ``any'' address,
and
0
otherwise.
Similarly,
unspecaddr
supplies, and
isunspecaddr
tests for,
the ``unspecified'' address,
which may be the same as the ``any'' address.
Similarly,
loopbackaddr
supplies, and
islookbackaddr
tests for,
the loopback address.
Anyaddr,
unspecaddr,
and
loopbackaddr
return
NULL
for success and
a pointer to a string-literal error message for failure;
see DIAGNOSTICS.

DIAGNOSTICS
Fatal errors in the address-supplying functions are:
unknown address family.
