     FGetC(UNIT, C)

FGetC: `INTEGER(KIND=1)' function.

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

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

Intrinsic groups: `badu77'.

Description:

   Reads a single character into C in stream mode from unit UNIT
(by-passing normal formatted output) using `getc(3)'.  Returns 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.
