curs_addchstr(3X) Library calls curs_addchstr(3X) 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 waddchstr(WINDOW *win, const chtype *chstr); int mvaddchstr(int y, int x, const chtype *chstr); int mvwaddchstr(WINDOW *win, int y, int x, const chtype *chstr); int addchnstr(const chtype *chstr, int n); int waddchnstr(WINDOW *win, const chtype *chstr, int n); int mvaddchnstr(int y, int x, const chtype *chstr, int n); 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 Curses does not specify any error conditions. This implementa- tion returns an error • if the win parameter is null or • if the wchstr parameter is null. Functions prefixed with "mv" first perform cursor movement and fail if the position (y, x) is outside the window boundaries. NOTES All functions except waddchnstr may be macros. PORTABILITY These functions are described in X/Open Curses, Issue 4.
