FGetC Intrinsic (subroutine)
............................

     CALL FGetC(UNIT, C, STATUS)

UNIT: `INTEGER'; scalar; INTENT(IN).

C: `CHARACTER'; scalar; INTENT(OUT).

STATUS: `INTEGER(KIND=1)'; OPTIONAL; scalar; INTENT(OUT).

Intrinsic groups: `unix'.

Description:

   Reads a single character into C in stream mode from unit UNIT
(by-passing normal formatted output) using `getc(3)'.  Returns in
STATUS 0 on success, -1 on end-of-file, and the error code from
`ferror(3)' otherwise.

   Stream I/O should not be mixed with normal record-oriented
(formatted or unformatted) I/O on the same unit; the results are
unpredictable.
