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. File mode
2. Inode number
3. ID of device containing directory entry for file
4. Device id (if relevant)
5. Number of links
6. Owner's uid
7. Owner's gid
8. File size (bytes)
9. Last access time
10. Last modification time
11. Last file status change time
12. Preferred I/O block size
13. Number of blocks allocated

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.
