\fBint addnstr(const char *\fIstr\fP, int \fIn\fP);
\fBint mvaddnstr(int \fIy\fP, int \fIx\fP, const char *\fIstr\fP, int \fIn\fP);
\fBint mvwaddnstr(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, const char *\fIstr\fP, int \fIn\fP);
\fBint waddnstr(WINDOW *\fIwin\fP, const char *\fIstr\fP, int \fIn\fP);
.fi
.SH DESCRIPTION
.B waddstr
writes the characters of the (null-terminated) string
.I str
to the window
.IR win .
Its process is similar to calling \fB\%waddch\fP(3X) for each
.I char
in
.IR str .
Control characters are processed as in \fB\%waddch\fP(3X).
.PP
.B waddnstr
writes at most
.I n
characters,
or until a terminating null character occurs in
.IR str .
If
.I n
is \-1,
.B
.B waddnstr
writes the entire string.
.PP
\fB\%ncurses\fP(3X) 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\%waddch\fP(3X) 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 \fBwaddnstr\fP may be macros.
.SH PORTABILITY
X/Open Curses,
Issue 4 describes these functions.
.SH SEE ALSO
\fB\%curs_addwstr\fP(3X) describes comparable functions of the
.I \%ncurses
library in its wide-character configuration
.RI ( \%ncursesw ).
