!!NAME


fclose - close a stream
!!SYNOPSIS


__#include __


__int fclose( FILE *__''stream''__);__
!!DESCRIPTION


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


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


__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


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


The __fclose__ function conforms to ANSI X3.159-1989
(``ANSI C'').
!!SEE ALSO


close(2), fcloseall(3), fflush(3),
fopen(3), setbuf(3)
