curs_addstr(3X)                                                curs_addstr(3X)

       addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr,
       mvwaddnstr - add a string of characters to a curses window and advance

       #include <curses.h>

       int addstr(const char *str);
       int addnstr(const char *str, int n);
       int waddstr(WINDOW *win, const char *str);
       int waddnstr(WINDOW *win, const char *str, int n);
       int mvaddstr(int y, int x, const char *str);
       int mvaddnstr(int y, int x, const char *str, int n);
       int mvwaddstr(WINDOW *win, int y, int x, const char *str);
       int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n);

       These functions write the (null-terminated) character string str on the
       given window.  It is similar to calling waddch once for each character
       in the string.

       The mv functions perform cursor movement once, before writing any
       characters.  Thereafter, the cursor is advanced as a side-effect of
       writing to the window.

       The four functions with n as the last argument write at most n
       characters, or until a terminating null is reached.  If n is -1, then
       the entire string will be added.

       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 or

        if the string pointer is null or

        if the corresponding calls to waddch return an error.

       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.

       All of these functions except waddnstr may be macros.

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

       curses(3X), curs_addch(3X).
