IPSEC_SUBNETOF(3)								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 similarly returns the host part, and broad-
       castof 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.

SEE ALSO
       inet(3), ipsec_atosubnet(3)

HISTORY
       Written for the FreeS/WAN project by Henry Spencer.

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