     <function>umask</function> sets PHP's umask to 
     <parameter>mask</parameter> &amp; 0777 and returns the old
     umask. When PHP is being used as a server module, the umask
     is restored when each request is finished.
    </para>
    <para>
     <function>umask</function> without arguments simply returns the
     current umask.
