      $semid = sem_get (  0xf01, 1, 0666 );
	  
      if ( !$semid ) {
         echo "mem.mem: Can't get semaphore<BR>";
         return;
      }
      if ( !sem_acquire( $semid ) ) {
         echo "mem.mem: Can't acquire semaphore<BR>";
         return;
      }
      if( !sem_release( $semid ) ) {
         echo "mem: Can't release semaphore";
      }
}
