IPSEC_SUBNETOF(3)					     Library Functions Manual						 IPSEC_SUBNETOF(3)

NAME
       ipsec_subnetof, ipsec_hostof, ipsec_broadcastof - given Internet address and subnet mask return subnet number, host part, broadcast address

SYNOPSIS
       #include <libreswan.h>

       struct in_addr subnetof(struct in_addr addr,
	   struct in_addr mask);
       struct in_addr hostof(struct in_addr addr,
	   struct in_addr mask);
       struct in_addr broadcastof(struct in_addr addr,
	   struct in_addr mask);

DESCRIPTION
       These functions are obsolete; see ipsec_networkof(3) for their replacements.

       Subnetof takes an Internet address and a subnet mask and returns the network part of the address (all in network byte order).  Hostof simi-
       larly returns the host part, and broadcastof returns the broadcast address (all-1s convention) for the network.

       These functions are provided to hide the Internet bit-munging inside an API, in hopes of easing the eventual transition to IPv6.

BUGS
       Calling functions for this is more costly than doing it yourself.
