  32 /*  FUNCTION
  33
  34     Stop an ExAll() operation before returning ERROR_NO_MORE_ENTRIES.
  35
  36     INPUTS
  37
  38     The inputs should correspond to the inputs for the ExAll() function.
  39
  40     lock     --  lock on the directory that is being examined
  41     buffer   --  buffer for data returned
  42     size     --  size of 'buffer' in bytes
  43     type     --  type of data to be returned
  44     control  --  control data structure
  45
  46     RESULT
  47
  48     NOTES
  49
  50     The control data structure must have been allocated with AllocDosObject().
