NAME
   Unix::setuid - Get/set real/effective UID/username via (localizeable)
   variable

VERSION
   This document describes version 0.02 of Unix::setuid (from Perl
   distribution Unix-setuid), released on 2014-10-09.

SYNOPSIS
    use Unix::setuid; # exports $RUID, $EUID, $RUSER, $EUSER
    say "Real      UID : $RUID";
    say "Effective UID : $EUID";
    say "Real username : $RUSER";
    say "Effective user: $EUSER";
    {
        # become UID 1000 temporarily
        local $EUID = 1000;
        # same thing
        #local $EUSER = "jajang"; # or 1000
    }
    # we're back to previous UID/user

DESCRIPTION
   This module is inspired by File::chdir and File::umask, using a tied
   scalar variable to get/set stuffs. One benefit of this is being able to
   use Perl's "local" with it, effectively setting something locally.

EXPORTS
 $RUID (real UID)
   This will get/set $<.

 $EUID (effective UID)
   This will get/set $>.

 $RUSER (real user)
   Same as $RUID except you will get username and you can set using
   UID/username. Will return numeric UID if no user exists with that ID.
   Will die if setting to non-existing username.

 $EUSER (effective user)
   Same as $EUID except you will get username and you can set using
   UID/username. Will return numeric UID if no user exists with that ID.
   Will die if setting to non-existing username.

SEE ALSO
   Perl's $< and $>.

   Other modules with the same concept: File::chdir, File::umask,
   Locale::Tie.
