    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.  

    SEE ALSO

    inet(3), ipsec_addrtot(3), ipsec_sameaddr(3)  

    DIAGNOSTICS

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