- This intrinsic function returns the file descriptor given a Fortran
- logical unit number.
-
- Success is indicated by a non-negative return value. A negative
- return value indicates an error. The value of _e_r_r_n_o can be examined
- to determine the cause of the error.

- NNOOTTEESS
- This function cannot be used on indexed files because each Fortran
- indexed file is represented by two physical files and this function
- cannot map a single Fortran logical unit to two file descriptors.
- Also, the indexed file internal format is proprietary and cannot be
- modified by the user directly; therefore, this function, or a similar
- function, will not help in that respect.
