    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.
