geteuid

       geteuid()  -  return the effective user id of an object or
       function

SYNOPSIS

       string geteuid( object|function );

DESCRIPTION

       If given an object argument, geteuid returns the effective
       user  id  (euid)  of  the object.  If given an argument of
       type 'function', it returns the euid of  the  object  that
       created  that  'function' variable.  If the object, at the
       time of the function variable's construction, had no euid,
       the object's uid is stored instead.
