### 8.234 `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 `VALUES`:

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

Arguments:

  NAME | The type shall be `CHARACTER`, of the default kind and a valid path within the file system.
  VALUES | 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
