### 8.94 `FSTAT` — Get file status

Description:
  `FSTAT` is identical to STAT, except that information about an already opened file is obtained.

  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 FSTAT(UNIT, VALUES [, STATUS])`
  `STATUS = FSTAT(UNIT, VALUES)`
