NAME    [Toc]    [Back]

       fclose - close a stream

SYNOPSIS    [Toc]    [Back]

       #include <stdio.h>

       int fclose( FILE *stream);

DESCRIPTION    [Toc]    [Back]

       The  fclose  function  dissociates the named stream from its underlying
       file or set of functions.  If the stream was being used for output, any
       buffered data is written first, using fflush(3).

RETURN VALUE    [Toc]    [Back]

       Upon  successful  completion 0 is returned.  Otherwise, EOF is returned
       and the global variable errno is set to indicate the error.  In	either
       case  any  further  access  (including another call to fclose()) to the
       stream results in undefined behaviour.

ERRORS    [Toc]    [Back]

       EBADF  The filedescriptor 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).

NOTES    [Toc]    [Back]

       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, e.g. with sync(2) or fsync(2).

CONFORMING TO    [Toc]    [Back]

       The fclose function conforms to ANSI X3.159-1989 (``ANSI C'').
