.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\\0\(aq), to \fIstream\fP.
|
|
.PP
|
|
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 NOTES
|
|
The behavior of
|
|
.BR fputws ()
|
|
depends on the
|
|
.B LC_CTYPE
|
|
category of the
|
|
current locale.
|
|
.PP
|
|
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.
