FUNCTION
<<fputws>>---write a wide character string in a file or stream
INDEX
fputws
INDEX
_fputws_r
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]>);
TRAD_SYNOPSIS
#include <wchar.h>
int fputws(<[ws]>, <[fp]>)
wchar_t *<[ws]>;
FILE *<[fp]>;
#include <wchar.h>
int _fputws_r(<[ptr]>, <[ws]>, <[fp]>)
struct _reent *<[ptr]>;
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
