  Name:                                                         printw

  Synopsis:
        int printw(const char *fmt, ...);
        int wprintw(WINDOW *win, const char *fmt, ...);
        int mvprintw(int y, int x, const char *fmt, ...);
        int mvwprintw(WINDOW *win, int y, int x, const char *fmt,...);
        int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
        int vw_printw(WINDOW *win, const char *fmt, va_list varglist);

  Description:
        The printw() functions add a formatted string to the window at 
        the current or specified cursor position. The format strings are 
        the same as used in the standard C library's printf(). (printw() 
        can be used as a drop-in replacement for printf().)

  Return Value:
        All functions return the number of characters printed, or 
        ERR on error.
