       15 +DESCRIPTION
  16   16       The Pisprocdir() function determines whether or not the directory dir is
  17   17       the root of the /proc file-system.  This works across loopback file
  18   18       system (lofs) mounts and chroots.

  20   20  RETURN VALUES
  21   21       Upon successful completion, the Pisprocdir() function returns 1 if dir is
  22   22       the /proc directory, otherwise if not, it returns 0.
