Manual page for FCLOSE(3V)
fclose, fflush - close or flush a stream
SYNOPSIS
#include <stdio.h>
fclose(stream)
FILE *stream;
fflush(stream)
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.3
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.
SYSTEM V DESCRIPTION
When
fflush()
is called on a stream opened for reading,
any unread data buffered in the stream is invalidated.
When
fflush()
is called on a stream opened for reading,
if the file is not already at
EOF,
and the file is one capable of seeking, the file offset of the underlying
open file description is adjusted so the next operation on the open file
description deals with the byte after the last byte read from or written
to the stream being flushed.
RETURN VALUES
fclose()
and
fflush()
return:
- 0
-
on success.
- EOF
-
if any error (such as trying to write to a file that
has not been opened for writing) was detected.
