ipsec sameaddr − are two addresses the same? |
#include <freeswan.h> int sameaddr(const ip_address *a, const ip_address
*b); |
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. |
