  27 /*  FUNCTION
  28         Conclude access to a message catalog, and decrement the use count.
  29         If this use count is 0, the catalog can be expunged when the
  30         system memory is running low.
  31
  32     INPUTS
  33         catalog        -        the message catalog to close, note that NULL is
  34                         a valid catalog.
  35
  36     RESULT
  37         The catalog is closed, and should no longer be used by the
  38         application.
