ipsec anyaddr - get "any" address
ipsec isanyaddr - test address for equality to "any" address

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);
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.
