    int inchnstr(chtype *ch, int n);
    int winchstr(WINDOW *win, chtype *ch);
    int winchnstr(WINDOW *win, chtype *ch, int n);
    int mvinchstr(int y, int x, chtype *ch);
    int mvinchnstr(int y, int x, chtype *ch, int n);
    int mvwinchstr(WINDOW *, int y, int x, chtype *ch);
    int mvwinchnstr(WINDOW *, int y, int x, chtype *ch, int n);

    int in_wchstr(cchar_t *wch);
    int in_wchnstr(cchar_t *wch, int n);
    int win_wchstr(WINDOW *win, cchar_t *wch);
    int win_wchnstr(WINDOW *win, cchar_t *wch, int n);
    int mvin_wchstr(int y, int x, cchar_t *wch);
    int mvin_wchnstr(int y, int x, cchar_t *wch, int n);
    int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wch);
    int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wch, int n);

### Description

   These routines read a chtype or cchar_t string from the window,
   starting at the current or specified position, and ending at the
   right margin, or after n elements, whichever is less.

### Return Value

   All functions return the number of elements read, or ERR on error.

### Portability
