User::grent(3)	       Perl Programmers	Reference Guide		User::grent(3)

NAME
       User::grent - by-name interface to Perl's built-in getgr*() functions

SYNOPSIS
	use User::grent;
	$gr = getgrgid(0) or die "No group zero";
	if ( $gr->name eq 'wheel' && @{$gr->members} > 1 ) {
	    print "gid zero name wheel,	with other members";
	}

	use User::grent	qw(:FIELDS);
	getgrgid(0) or die "No group zero";
	if ( $gr_name eq 'wheel' && @gr_members	> 1 ) {
	    print "gid zero name wheel,	with other members";
	}

	$gr = getgr($whoever);

DESCRIPTION
       This module's default exports override the core getgrent(), getgruid(),
       and getgrnam() functions, replacing them	with versions that return
       "User::grent" objects.  This object has methods that return the
       similarly named structure field name from the C's passwd	structure from
       grp.h; namely name, passwd, gid,	and members (not mem).	The first
       three return scalars, the last an array reference.

       You may also import all the structure fields directly into your
       namespace as regular variables using the	:FIELDS	import tag.  (Note
       that this still overrides your core functions.)	Access these fields as
       variables named with a preceding	"gr_".	Thus, "$group_obj->gid()"
       corresponds to $gr_gid if you import the	fields.	 Array references are
       available as regular array variables, so	"@{ $group_obj->members() }"
       would be	simply @gr_members.

       The getpw() function is a simple	front-end that forwards	a numeric
       argument	to getpwuid() and the rest to getpwnam().

       To access this functionality without the	core overrides,	pass the "use"
       an empty	import list, and then access function functions	with their
       full qualified names.  On the other hand, the built-ins are still
       available via the "CORE::" pseudo-package.

NOTE
       While this class	is currently implemented using the Class::Struct
       module to build a struct-like class, you	shouldn't rely upon this.
