.SH NAME
fputws \- write a wide-character string to a FILE stream
.SH LIBRARY
Standard C library
.RI ( libc ", " \-lc )
.SH SYNOPSIS
.nf
.B #include <wchar.h>
.P
.BI "int fputws(const wchar_t *restrict " ws ", FILE *restrict " stream );
.fi
.SH DESCRIPTION
The
.BR fputws ()
function is the wide-character equivalent of
the
.BR fputs (3)
function.
It writes the wide-character string starting at \fIws\fP,
up to but not including the terminating null wide character (L\[aq]\e0\[aq]),
to \fIstream\fP.
.P
For a nonlocking counterpart, see
.BR unlocked_stdio (3).
.SH RETURN VALUE
The
.BR fputws ()
function returns a
nonnegative integer if the operation was
successful, or \-1 to indicate an error.
.SH ATTRIBUTES
For an explanation of the terms used in this section, see
.BR attributes (7).

.SH STANDARDS
C11, POSIX.1-2008.
.SH HISTORY
POSIX.1-2001, C99.
.SH NOTES
The behavior of
.BR fputws ()
depends on the
.B LC_CTYPE
category of the
current locale.
.P
In the absence of additional information passed to the
.BR fopen (3)
call, it is
reasonable to expect that
.BR fputws ()
will actually write the multibyte
string corresponding to the wide-character string \fIws\fP.
