### Synopsis

    int addchstr(const chtype *ch);
    int addchnstr(const chtype *ch, int n);
    int waddchstr(WINDOW *win, const chtype *ch);
    int waddchnstr(WINDOW *win, const chtype *ch, int n);
    int mvaddchstr(int y, int x, const chtype *ch);
    int mvaddchnstr(int y, int x, const chtype *ch, int n);
    int mvwaddchstr(WINDOW *, int y, int x, const chtype *ch);
    int mvwaddchnstr(WINDOW *, int y, int x, const chtype *ch, int n);

    int add_wchstr(const cchar_t *wch);
    int add_wchnstr(const cchar_t *wch, int n);
    int wadd_wchstr(WINDOW *win, const cchar_t *wch);
    int wadd_wchnstr(WINDOW *win, const cchar_t *wch, int n);
    int mvadd_wchstr(int y, int x, const cchar_t *wch);
    int mvadd_wchnstr(int y, int x, const cchar_t *wch, int n);
    int mvwadd_wchstr(WINDOW *win, int y, int x, const cchar_t *wch);
    int mvwadd_wchnstr(WINDOW *win, int y, int x, const cchar_t *wch,
                       int n);

### Description

   These routines write a chtype or cchar_t string directly into the
   window structure, starting at the current or specified position. The
   four routines 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
   string is copied, up to the maximum number that will fit on the line.

   The cursor position is not advanced. These routines do not check for
   newline or other special characters, nor does any line wrapping
   occur.

### Return Value

   All functions return OK or ERR.
