Method: Curses::Window#nodelay=

Defined in:
ext/curses/curses.c

#nodelay=(bool) ⇒ Object

When in no-delay mode Curses::Window#getch is a non-blocking call. If no input is ready #getch returns ERR.

When in delay mode (bool is false which is the default), Curses::Window#getch blocks until a key is pressed.
