fclose — close a stream
#include <stdio.h>
int
fclose( |
FILE *stream) ; |
The fclose
() function
flushes the stream pointed to by stream
(writing any buffered
output data using fflush(3)) and closes the
underlying file descriptor.
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.
The file descriptor underlying stream
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).
For an explanation of the terms used in this section, see attributes(7).

Note that fclose
() flushes
only 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).
