NAME
fclose - close a stream
SYNOPSIS
#include <stdio.h>
int fclose(FILE *fp);
DESCRIPTION
The fclose() function 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).
