8.11.9.114 FStat Intrinsic (function)

FStat(Unit, SArray)

FStat: INTEGER(KIND=1) function.

Unit: INTEGER; scalar; INTENT(IN).

SArray: INTEGER(KIND=1); DIMENSION(13); 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.

Returns 0 on success or a non-zero error code.
