### 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.
