+FUNCTION
+<<putw>>---write a word (int)
+
+INDEX
+	putw
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int putw(int <[w]>, FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int putw(<w>, <[fp]>)
+	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>>.
