$OpenBSD: OpenBSD::IdCache.pod,v 1.2 2005/06/13 11:33:07 espie Exp $
=head1 NAME
OpenBSD::IdCache - cache for user and group look-ups
=head1 SYNOPSIS
use OpenBSD::IdCache;
my $ucache = new OpenBSD::UidCache;
my $uid = $ucache->lookup("espie");
my $gcache = new OpenBSD::GidCache;
my $gid = $gcache->lookup("wheel", 0);
my $unamecache = new OpenBSD::UnameCache;
my $name = $unamecache->lookup($uid);
my $gnamecache = new OpenBSD::GnameCache;
my $grname = $gnamecache->lookup($gid);
=head1 DESCRIPTION
C<OpenBSD::IdCache> provides four classes: C<OpenBSD::UidCache> for UIDs,
C<OpenBSD::GidCache> for GIDs, C<OpenBSD::UnameCache> for user names, and
C<OpenBSD::GnameCache> for group names.
C<UidCache::new> creates a UID cache, which can be used to look up user
names by using the C<lookup> method. Looking up a numeric user name
is a no-op. Non-existing IDs return a default value, which is normally
C<undef> but can be provided as an extra argument to C<lookup>.
C<GidCache::new> provides the same service for GIDs.
C<UnameCache::new> creates a user name cache, which can be used to look up
UIDs.
C<GnameCache::new> provides the same service for group names.
