FUNCTION
<<fflush>>---flush buffered file output
INDEX
fflush
ANSI_SYNOPSIS
#include <stdio.h>
int fflush(FILE *<[fp]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fflush(<[fp]>)
FILE *<[fp]>;
DESCRIPTION
The <<stdio>> output functions can buffer output before delivering it
to the host system, in order to minimize the overhead of system calls.
Use <<fflush>> to deliver any such pending output (for the file
or stream identified by <[fp]>) to the host system.
If <[fp]> is <<NULL>>, <<fflush>> delivers pending output from all
open files.
RETURNS
<<fflush>> returns <<0>> unless it encounters a write error; in that
situation, it returns <<EOF>>.
PORTABILITY
ANSI C requires <<fflush>>.
No supporting OS subroutines are required.
