+ANSI_SYNOPSIS
+	#include <wchar.h>
+	int fputws(const wchar_t *<[ws]>, FILE *<[fp]>);
+
+	#include <wchar.h>
+	int _fputws_r(struct _reent *<[ptr]>, const wchar_t *<[ws]>, FILE *<[fp]>);

+
+DESCRIPTION
+<<fputws>> writes the wide character string at <[ws]> (but without the
+trailing null) to the file or stream identified by <[fp]>.
+
+<<_fputws_r>> is simply the reentrant version of <<fputws>> that takes
+an additional reentrant struct pointer argument: <[ptr]>.
+
+RETURNS
+If successful, the result is a non-negative integer; otherwise, the result
+is <<-1>> to indicate an error.
+
+PORTABILITY
+C99, POSIX.1-2001
