NAME
fclose - close a stream
SYNOPSIS
#include <stdio.h>
int fclose(FILE *fp);
DESCRIPTION
The
fclose()
function will flushes the stream pointed to by
fp
(writing any buffered output data using
fflush(3))
and closes the underlying file descriptor.
RETURN VALUE
Upon successful completion 0 is returned.
Otherwise,
EOF
is returned and
errno
is set to indicate the error.
In either case any further access
(including another call to
fclose())
to the stream results in undefined behavior.
ERRORS
- EBADF
-
The file descriptor underlying
fp
is not valid.
The
fclose()
function may also fail and set
errno
for any of the errors specified for the routines
close(2),
write(2)
or
fflush(3).
CONFORMING TO
C89, C99.
NOTES
Note that
fclose()
only flushes the user space buffers provided by the
C library.
To ensure that the data is physically stored
on disk the kernel buffers must be flushed too, for example, with
sync(2)
or
fsync(2).
