FUNCTION
|
|
<<putw>>---write a word (int)
|
|
|
|
INDEX
|
|
putw
|
|
|
|
SYNOPSIS
|
|
#include <stdio.h>
|
|
int putw(int <[w]>, FILE *<[fp]>);
|
|
|
|
DESCRIPTION
|
|
<<putw>> is a function, defined in <<stdio.h>>. You can use <<putw>>
|
|
to write a word to the file or stream identified by <[fp]>. As a side
|
|
effect, <<putw>> advances the file's current position indicator.
|
|
|
|
RETURNS
|
|
Zero on success, <<EOF>> on failure.
|
|
|
|
PORTABILITY
|
|
<<putw>> is a remnant of K&R C; it is not part of any ISO C Standard.
|
|
<<fwrite>> should be used instead. In fact, this implementation of
|
|
<<putw>> is based upon <<fwrite>>.
|
|
|
|
Supporting OS subroutines required: <<fwrite>>.
