    NAME

    ipsec sameaddr - are two addresses the same?
    
    ipsec addrcmp - ordered comparison of addresses
    ipsec samesubnet - are two subnets the same?
    ipsec addrinsubnet - is an address within a subnet?
    ipsec subnetinsubnet - is a subnet within another subnet?
    ipsec subnetishost - is a subnet a single host?
    ipsec samesaid - are two SA IDs the same?
    ipsec sameaddrtype - are two addresses of the same address family?
    ipsec samesubnettype - are two subnets of the same address family?  

    SYNOPSIS

    #include <freeswan.h>

    int sameaddr(const ip_address *a, const ip_address *b);
    int addrcmp(const ip_address *a, const ip_address *b);
    int samesubnet(const ip_subnet *a, const ip_subnet *b);
    int addrinsubnet(const ip_address *a, const ip_subnet *s);
    int subnetinsubnet(const ip_subnet *a, const ip_subnet *b);
    int subnetishost(const ip_subnet *s);
    int samesaid(const ip_said *a, const ip_said *b);
    int sameaddrtype(const ip_address *a, const ip_address *b);
    int samesubnettype(const ip_subnet *a, const ip_subnet *b);  

    DESCRIPTION

    These functions do various comparisons and tests on the ip_address type and ip_subnet types.

    Sameaddr returns non-zero if addresses a and b are identical, and 0 otherwise. Addresses of different families are never identical.

    Addrcmp returns -1, 0, or 1 respectively if address a is less than, equal to, or greater than b. If they are not of the same address family, they are never equal; the ordering reported in this case is arbitrary (and probably not useful) but consistent.

    Samesubnet returns non-zero if subnets a and b are identical, and 0 otherwise. Subnets of different address families are never identical.

    Addrinsubnet returns non-zero if address a is within subnet s and 0 otherwise. An address is never within a subnet of a different address family.

    Subnetinsubnet returns non-zero if subnet a is a subset of subnet b and 0 otherwise. A subnet is deemed to be a subset of itself. A subnet is never a subset of another subnet if their address families differ.

    Subnetishost returns non-zero if subnet s is in fact only a single host, and 0 otherwise.

    Samesaid returns non-zero if SA IDs a and b are identical, and 0 otherwise.

    Sameaddrtype returns non-zero if addresses a and b are of the same address family, and 0 otherwise.

    Samesubnettype returns non-zero if subnets a and b are of the same address family, and 0 otherwise.
