FGETC(3f)

DESCRIPTION
Read a single character in stream mode by bypassing normal formatted output. Stream I/O should not be mixed with normal record-oriented (formatted or unformatted) I/O on the same unit; the results are unpredictable.

This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit.

Note that the FGET intrinsic is provided for backwards compatibility with g77. GNU Fortran provides the Fortran 2003 Stream facility. Programmers should consider the use of new stream IO feature in new code for future portability.

STANDARD
GNU extension

CLASS
Subroutine, function

SYNTAX

CALL FGETC(UNIT, C [, STATUS]) STATUS = FGETC(UNIT, C)

ARGUMENTS

UNIT The type shall be INTEGER. C The type shall be CHARACTER and of default kind. STATUS (Optional) status flag of type INTEGER. Returns 0 on success, -1 on end-of-file and a system specific positive error code otherwise.

EXAMPLE
          PROGRAM test_fgetc
            INTEGER :: fd = 42, status
            CHARACTER :: c

            OPEN(UNIT=fd, FILE="/etc/passwd", ACTION="READ", STATUS = "OLD")
            DO
              CALL fgetc(fd, c, status)
              IF (status /= 0) EXIT
              call fput(c)
            END DO
            CLOSE(UNIT=fd)
          END PROGRAM
