FStat Intrinsic (subroutine)
............................

     CALL FStat(UNIT, SARRAY, STATUS)

UNIT: `INTEGER'; scalar; INTENT(IN).

SARRAY: `INTEGER(KIND=1)'; DIMENSION(13); INTENT(OUT).

STATUS: `INTEGER(KIND=1)'; OPTIONAL; scalar; INTENT(OUT).

Intrinsic groups: `unix'.

Description:

   Obtains data about the file open on Fortran I/O unit UNIT and places
them in the array SARRAY.  The values in this array are extracted from
the `stat' structure as returned by `fstat(2)' q.v., as follows:

  1. Device ID

  2. Inode number

  3. File mode

  4. Number of links

  5. Owner's uid

  6. Owner's gid

  7. ID of device containing directory entry for file (0 if not
     available)

  8. File size (bytes)

  9. Last access time

 10. Last modification time

 11. Last file status change time

 12. Preferred I/O block size (-1 if not available)

 13. Number of blocks allocated (-1 if not available)

   Not all these elements are relevant on all systems.  If an element
is not relevant, it is returned as 0.

   If the STATUS argument is supplied, it contains 0 on success or a
non-zero error code upon return.

   Some non-GNU implementations of Fortran provide this intrinsic as
only a function, not as a subroutine, or do not support the (optional)
STATUS argument.
