+.TH IPSEC_SUBNETOF 3 "11 June 2001"
+.\" RCSID $Id: subnetof.3,v 1.1 2004/03/15 20:35:26 as Exp $
+.SH NAME
+ipsec subnetof \- given Internet address and subnet mask, return subnet number
+.br
+ipsec hostof \- given Internet address and subnet mask, return host part
+.br
+ipsec broadcastof \- given Internet address and subnet mask, return broadcast address
+.SH SYNOPSIS
+.B "#include <freeswan.h>
+.sp
+.B "struct in_addr subnetof(struct in_addr addr,"
+.ti +1c
+.B "struct in_addr mask);"
+.br
+.B "struct in_addr hostof(struct in_addr addr,"

+.B "struct in_addr mask);"
+.SH DESCRIPTION
+These functions are obsolete; see
+.IR ipsec_networkof (3)
+for their replacements.
+.PP
+.I Subnetof
+takes an Internet
+.I address
+and a subnet
+.I mask
+and returns the network part of the address
+(all in network byte order).
+.I Hostof
+similarly returns the host part, and
+.I broadcastof
+returns the broadcast address (all-1s convention) for the network.
+.PP
+These functions are provided to hide the Internet bit-munging inside
+an API, in hopes of easing the eventual transition to IPv6.
+.SH SEE ALSO
+inet(3), ipsec_atosubnet(3)
+.SH HISTORY
+Written for the FreeS/WAN project by Henry Spencer.
+.SH BUGS
+Calling functions for this is more costly than doing it yourself.
