  10
  11   Synopsis:
  12         int printw(const char *fmt, ...);
  13         int wprintw(WINDOW *win, const char *fmt, ...);
  14         int mvprintw(int y, int x, const char *fmt, ...);
  15         int mvwprintw(WINDOW *win, int y, int x, const char *fmt,...);
  16         int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
  17         int vw_printw(WINDOW *win, const char *fmt, va_list varglist);
  18
  19   Description:
  20         The printw() functions add a formatted string to the window at
  21         the current or specified cursor position. The format strings are
  22         the same as used in the standard C library's printf(). (printw()
  23         can be used as a drop-in replacement for printf().)
  24
  25   Return Value:
  26         All functions return the number of characters printed, or
  27         ERR on error.
