6.201 STAT — Get file status

Description:

This function returns information about a file. No permissions are required on the file itself, but execute (search) permission is required on all of the directories in path that lead to the file.

The elements that are obtained and stored in the array BUFF:

buff(1)	Device ID
buff(2)	Inode number
buff(3)	File mode
buff(4)	Number of links
buff(5)	Owner's uid
buff(6)	Owner's gid
buff(7)	ID of device containing directory entry for file (0 if not available)
buff(8)	File size (bytes)
buff(9)	Last access time
buff(10)	Last modification time
buff(11)	Last file status change time
buff(12)	Preferred I/O block size (-1 if not available)
buff(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.

This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit.

Standard:

GNU extension

Class:

Subroutine, function

Syntax:

CALL STAT(FILE,BUFF[,STATUS])

Arguments:

FILE	The type shall be CHARACTER(*), a valid path within the file system.
BUFF	The type shall be INTEGER(4), DIMENSION(13).
STATUS	(Optional) status flag of type INTEGER(4). Returns 0 on success and a system specific error code otherwise.

Example:

          PROGRAM test_stat
            INTEGER, DIMENSION(13) :: buff
            INTEGER :: status
          
            CALL STAT("/etc/passwd", buff, status)
          
            IF (status == 0) THEN
              WRITE (*, FMT="('Device ID:',               T30, I19)") buff(1)
              WRITE (*, FMT="('Inode number:',            T30, I19)") buff(2)
              WRITE (*, FMT="('File mode (octal):',       T30, O19)") buff(3)
              WRITE (*, FMT="('Number of links:',         T30, I19)") buff(4)
              WRITE (*, FMT="('Owner''s uid:',            T30, I19)") buff(5)
              WRITE (*, FMT="('Owner''s gid:',            T30, I19)") buff(6)
              WRITE (*, FMT="('Device where located:',    T30, I19)") buff(7)
              WRITE (*, FMT="('File size:',               T30, I19)") buff(8)
              WRITE (*, FMT="('Last access time:',        T30, A19)") CTIME(buff(9))
              WRITE (*, FMT="('Last modification time',   T30, A19)") CTIME(buff(10))
              WRITE (*, FMT="('Last status change time:', T30, A19)") CTIME(buff(11))
              WRITE (*, FMT="('Preferred block size:',    T30, I19)") buff(12)
              WRITE (*, FMT="('No. of blocks allocated:', T30, I19)") buff(13)
            END IF
          END PROGRAM
