NAME

       addchstr,  addchnstr,  waddchstr,  waddchnstr, mvaddchstr, mvaddchnstr, mvwaddchstr, mvwaddchnstr - add a
       curses character string to a window

SYNOPSIS

       #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

       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 are 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

       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 win parameter is null or

       •   if the wchstr parameter 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

       All functions except waddchnstr may be macros.

PORTABILITY

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