FUNCTION
<<fputws>>, <<fputws_unlocked>>---write a wide character string in a file or stream
INDEX
fputws
INDEX
fputws_unlocked
INDEX
_fputws_r
INDEX
_fputws_unlocked_r
SYNOPSIS
#include <wchar.h>
int fputws(const wchar_t *__restrict <[ws]>, FILE *__restrict <[fp]>);
#define _GNU_SOURCE
#include <wchar.h>
int fputws_unlocked(const wchar_t *__restrict <[ws]>, FILE *__restrict <[fp]>);
#include <wchar.h>
int _fputws_r(struct _reent *<[ptr]>, const wchar_t *<[ws]>,
FILE *<[fp]>);
#include <wchar.h>
int _fputws_unlocked_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_unlocked>> is a non-thread-safe version of <<fputws>>.
<<fputws_unlocked>> may only safely be used within a scope
protected by flockfile() (or ftrylockfile()) and funlockfile(). This
function may safely be used in a multi-threaded program if and only
if they are called while the invoking thread owns the (FILE *)
object, as is the case after a successful call to the flockfile() or
ftrylockfile() functions. If threads are disabled, then
<<fputws_unlocked>> is equivalent to <<fputws>>.
<<_fputws_r>> and <<_fputws_unlocked_r>> are simply reentrant versions of the
above that take 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
<<fputws>> is required by C99 and POSIX.1-2001.
<<fputws_unlocked>> is a GNU extension.
