  28 /*  FUNCTION
  29
  30     Fill in a FileInfoBlock structure concerning a file or directory
  31     associated with a particular lock.
  32
  33     INPUTS
  34
  35     lock  --  lock to examine
  36     fib   --  FileInfoBlock where the result of the examination is stored
  37
  38     RESULT
  39
  40     A boolean telling whether the operation was successful or not.
  41
  42     NOTES
  43
  44     FileInfoBlocks should be allocated with AllocDosObject(). You may make
  45     a copy of the FileInfoBlock but, however, this copy may NOT be passed
  46     to ExNext()!
