.SH SYNOPSIS
.nf
\fB#include <curses.h>
.PP
\fBint addchstr(const chtype *\fIchstr\fP);
\fBint waddchstr(WINDOW *\fIwin\fP, const chtype *\fIchstr\fP);
\fBint mvaddchstr(int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP);
\fBint mvwaddchstr(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP);
.PP
\fBint addchnstr(const chtype *\fIchstr\fP, int \fIn\fP);
\fBint waddchnstr(WINDOW *\fIwin\fP, const chtype *\fIchstr\fP, int \fIn\fP);
\fBint mvaddchnstr(int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP, int \fIn\fP);
\fBint mvwaddchnstr(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP, int \fIn\fP);
.fi
.SH DESCRIPTION
These functions copy the (null-terminated)
\fIchstr\fP array
into the window image structure
starting at the current cursor position.
.PP
The four functions with \fIn\fP as the last
argument copy at most \fIn\fP elements,
but no more than will fit on the line.
If \fBn\fP=\fB\-1\fP then the whole array is copied,
to the maximum number of characters that will fit on the line.
.PP
The window cursor is \fInot\fP advanced.
These functions are faster than \fBwaddnstr\fP.
On the other hand:
.bP
they do not perform checking
(such as for the newline, backspace, or carriage return characters),
.bP
they do not advance the current cursor position,
.bP
they do not expand other control characters to ^-escapes, and
.bP
they truncate the string if it crosses the right margin,
rather than wrapping it around to the new line.
.SH RETURN VALUE
All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
.PP
X/Open Curses does not specify any error conditions.
This implementation returns an error
.bP
if the \fIwin\fP parameter is null or
.bP
if the \fIwchstr\fP parameter is null.
.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 functions except \fBwaddchnstr\fP may be macros.
.SH PORTABILITY
These functions are described in X/Open Curses, Issue 4.
.SH SEE ALSO
\fB\%curs_add_wchstr\fP(3X) describes comparable functions of the
.I \%ncurses
library in its wide-character configuration
.RI ( \%ncursesw ).
