Manual page for FCLOSE(3S)
fclose, fflush - close or flush a stream
SYNOPSIS
#include <stdio.h>
int fclose(FILE *stream);
int fflush(FILE *stream);
DESCRIPTION
Fclose
causes any buffers for the named
stream
to be flushed, and the file to be closed.
Buffers allocated by the standard input/output system
are freed.
Fclose
is performed automatically upon
calling
exit.3
Fflush
causes any buffered data for the named output or update
stream
to be written to that file.
The stream remains open.
If
stream
is a null pointer, the
fflush
function performs this flushing action on all
output and update streams.
RETURN VALUE
Fclose
and
fflush
return EOF for unsuccessful calls and store an error code in
errno,
otherwise returning zero.
