NAME

fclose, fflush - close or flush a stream

SYNOPSIS

#include <stdio.h>

int fclose(FILE *stream);

int fflush(FILE *stream);

DESCRIPTION

fclose writes out any buffered data for the named stream, and closes the named stream. Buffers allocated by the standard input/output system are freed. fclose is performed automatically for all open files upon calling exit. fflush writes any unwritten data for an output stream or an update stream in which the most recent operation was not input to be delivered to the host environment to the file; otherwise it is ignored. The named stream remains open.

RETURN VALUES

fclose returns:
  0 on success. EOF if any error (such as trying to write to a file that

    has not been opened for writing) was detected. fflush returns:
  0 on success or if the file wasn't open. EOF if an error was detected while writing the data.
