19 FUNCTION
20 <<putw>>---write a word (int)
21 
22 INDEX
23 	putw
24 
25 SYNOPSIS
26 	#include <stdio.h>
27 	int putw(int <[w]>, FILE *<[fp]>);
28 
29 DESCRIPTION
30 <<putw>> is a function, defined in <<stdio.h>>.  You can use <<putw>>
31 to write a word to the file or stream identified by <[fp]>.  As a side
32 effect, <<putw>> advances the file's current position indicator.
33 
34 RETURNS
35 Zero on success, <<EOF>> on failure.
36 
37 PORTABILITY
38 <<putw>> is a remnant of K&R C; it is not part of any ISO C Standard.
39 <<fwrite>> should be used instead.  In fact, this implementation of
40 <<putw>> is based upon <<fwrite>>.
41 
42 Supporting OS subroutines required: <<fwrite>>.
