.func flushall
#include <stdio.h>
int flushall( void );
.ixfunc2 '&StrIo' &func
.funcend
.desc begin
The &func function clears all buffers associated with input streams
and writes any buffers associated with output streams.
A subsequent read operation on an input file causes new data
to be read from the associated file or device.
.np
Calling the &func function is equivalent to calling the
.kw fflush
for all open stream files.
.desc end
.return begin
The &func function returns the number of open streams.
When an output error occurs while writing to a file, the
.kw errno
global variable will be set.
