curs_addstr(3X) Library calls curs_addstr(3X) NAME addstr, waddstr, mvaddstr, mvwaddstr, addnstr, waddnstr, mvaddnstr, mvwaddnstr - add a string to a curses window and advance the cursor SYNOPSIS #include <curses.h> int addstr(const char * str); int waddstr(WINDOW * win, const char * str); int mvaddstr(int y, int x, const char * str); int mvwaddstr(WINDOW * win, int y, int x, const char * str); int addnstr(const char * str, int n); int waddnstr(WINDOW * win, const char * str, int n); int mvaddnstr(int y, int x, const char * str, int n); int mvwaddnstr(WINDOW * win, int y, int x, const char * str, int n); DESCRIPTION waddstr writes the characters of the (null-terminated) string str to the window win, as if by calling waddch(3X) for each char in str. waddnstr is similar, but writes at most n characters. If n is -1, waddnstr writes the entire string. ncurses(3X) describes the variants of these functions. RETURN VALUE These functions return OK on success and ERR on failure. In ncurses, these functions fail if • the curses screen has not been initialized, • str is a null pointer, • (for functions taking a WINDOW pointer argument) win is a null pointer, or • an internal waddch(3X) call returns ERR. Functions prefixed with "mv" first perform cursor movement and fail if the position (y, x) is outside the window boundaries. NOTES All of these functions except waddnstr may be implemented as macros. PORTABILITY X/Open Curses Issue 4 describes these functions. It specifies no error conditions for them. SVr4 describes a successful return value only as "an integer value other than ERR". HISTORY 4BSD (1980) introduced waddstr along with its variants, the latter de- fined as macros. SVr3.1 (1987) added waddnstr (and its variants) redefining waddstr as a macro wrapping it.
