Hello,

  I have a couple questions regaurding shared memory and semaphores.

  1)  I've created a shared memory area using shmget and my processes
      can communicate correctly.  However, it is possible for any one of
      the processes to remove the partion even though the others are still
      using it.  The processes are all running under the same user so any
      process has permission to remove it.  Is there a way to prevent the
      removal if the memory is still in use?

  2)  I need the ability to lock out a portion of shared memory in
      some critical regions of the code.  Is it possible using semget and
      semctl to do this?  Again, the processes using the shared memory are
      running under the same user.


      Thanks,
