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.
