FCLOSE(3S)                                             FCLOSE(3S)

     NAME
          fclose, fflush - close or flush a stream

     SYNOPSIS
          #include <stdio.h>

          fclose(stream)
          FILE *stream;

          fflush(stream)
          FILE *stream;

     DESCRIPTION
          Fclose causes any buffers for the named stream to be emp-
          tied, and the file to be closed.  Buffers allocated by the
          standard input/output system are freed.

          Fclose is performed automatically upon calling exit(2).

          Fflush causes any buffered data for the named output stream
          to be written to that file.  The stream remains open.

     SEE ALSO
          close(2), fopen(3), setbuf(3)

     DIAGNOSTICS
          These routines return EOF if stream is not associated with
          an output file, or if buffered data cannot be transferred to
          that file.
