  Name:                                                         inchstr

  Synopsis:
        int inchstr(chtype *ch);
        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.
