  Name:                                                         addstr

  Synopsis:
        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);

        int addwstr(const wchar_t *wstr);
        int addnwstr(const wchar_t *wstr, int n);
        int waddwstr(WINDOW *win, const wchar_t *wstr);
        int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);
        int mvaddwstr(int y, int x, const wchar_t *wstr);
        int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
        int mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *wstr);
        int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);

  Description:
        These routines write all the characters of the null-terminated
        string str or wide-character string wstr to the given window.
        The functionality is similar to calling waddch() once for each
        character in the string; except that, when PDCurses is built
        with wide-character support enabled, the narrow-character
        functions treat the string as a multibyte string in the current
        locale, and convert it. The routines with n as the last
        argument write at most n characters; if n is negative, then the
        entire string will be added.

  Return Value:
        All functions return OK or ERR.
