.fi
.SH DESCRIPTION
.B waddwstr
writes the characters of the (wide-null-terminated) wide-character
string
.I wstr
to the window
.IR win .
Its process is similar to constructing a
.I cchar_t
for each
.I wchar_t
in
.IR wstr ,
then calling \fB\%wadd_wch\fP(3NCURSES) with the resulting
.IR cchar_t .
.bP
Spacing and non-spacing characters in the string
are processed one at a time,
and
.bP
control characters are processed as in \fB\%wadd_wch\fP(3NCURSES).
.PP
.B waddnwstr
writes at most
.I n
wide characters,
or until a terminating wide null character occurs in
.IR wstr .
If
.I n
is \-1,
.B
.B waddnwstr
writes the entire wide string.
.PP
\fB\%ncurses\fP(3NCURSES) describes the variants of these functions.
.SH RETURN VALUE
These functions return
.B OK
on success and
.B ERR
on failure.
.PP
X/Open Curses does not specify any error conditions.
.I \%ncurses
returns an error
.bP
if the window pointer is
.BR NULL ,
.bP
if the string pointer is
.BR NULL ,
or
.bP
if an internal \fB\%wadd_wch\fP(3NCURSES) call returns an error.
.PP
Functions prefixed with \*(``mv\*('' first perform cursor movement and
fail if the position
.RI ( y ,
.IR x )
is outside the window boundaries.
.SH NOTES
All of these functions except
.B waddnwstr
may be implemented as macros.
.SH PORTABILITY
X/Open Curses,
Issue 4 describes these functions.
.SH SEE ALSO
\fB\%addstr\fP(3NCURSES) describes comparable functions of the
.I \%ncurses
library in its non-wide-character configuration.
