curs_addchstr(3X)                                          curs_addchstr(3X)

NAME         top

       addchstr, addchnstr, waddchstr, waddchnstr, mvaddchstr, mvaddchnstr,
       mvwaddchstr, mvwaddchnstr - add a string of characters (and
       attributes) to a curses window

SYNOPSIS         top

       #include <curses.h>

       int addchstr(const chtype *chstr);
       int addchnstr(const chtype *chstr, int n);
       int waddchstr(WINDOW *win, const chtype *chstr);
       int waddchnstr(WINDOW *win, const chtype *chstr, int n);
       int mvaddchstr(int y, int x, const chtype *chstr);
       int mvaddchnstr(int y, int x, const chtype *chstr, int n);
       int mvwaddchstr(WINDOW *win, int y, int x, const chtype *chstr);
       int mvwaddchnstr(WINDOW *win, int y, int x, const chtype *chstr, int n);

DESCRIPTION         top

       These functions copy the (null-terminated) chstr array into the
       window image structure starting at the current cursor position.  The
       four functions with n as the last argument copy at most n elements,
       but no more than will fit on the line.  If n=-1 then the whole array
       is copied, to the maximum number of characters that will fit on the
       line.

       The window cursor is not advanced.  These functions work faster than
       waddnstr.  On the other hand:

       ·   they do not perform checking (such as for the newline, backspace,
           or carriage return characters),

       ·   they do not advance the current cursor position,

       ·   they do not expand other control characters to ^-escapes, and

       ·   they truncate the string if it crosses the right margin, rather
           than wrapping it around to the new line.

RETURN VALUE         top

       All functions return the integer ERR upon failure and OK on success.

       X/Open does not define any error conditions.  This implementation
       returns an error if the window pointer is null.

       Functions with a "mv" prefix first perform a cursor movement using
       wmove, and return an error if the position is outside the window, or
       if the window pointer is null.

NOTES         top

       All functions except waddchnstr may be macros.

PORTABILITY         top

       These entry points are described in the XSI Curses standard, Issue 4.

SEE ALSO         top

       curs_addstr(3X), curses(3X).

       Comparable functions in the wide-character (ncursesw) library are
       described in curs_add_wchstr(3X).
