.SH DESCRIPTION
|
||
The

||
.BR fflush (3).
|
||
Note that the standard streams (stdin, stdout
|
||
and stderr) are also closed.
|
||
.SH "RETURN VALUE"
|
||
This function always returns 0.
|
||
.SH "SEE ALSO"
|
||
.BR close (2),
|
||

||
.BR fflush (3),
|
||
.BR fopen (3),
|
||
.BR setbuf (3)
|
||
.SH "CONFORMING TO"
|
||

|
||
.BR fcloseall ()
|
||
function is a GNU extension.
