  • `wgetch()` expect a `WINDOW` reference/pointer, `getch()` does not. Check the parameter lists of these function. – Progman Jan 03 '21 at 17:58
  • @Progman This doesn't answer the question. What's the purpose of this parameter? – martinkunev Jul 29 '21 at 19:41
  • Most likely to reference a `WINDOW` instance from the ncurses library. Check https://code.woboq.org/linux/include/curses.h.html#WINDOW for its definition and the documentation of the available ncurse functions which work with `WINDOW` parameters. – Progman Jul 29 '21 at 19:47

getch() is equivalent to wgetch(stdscr). The function wgetch does wrefresh of the specified window and then reads input. So getch() would refresh stdscr and then wait for input.
