nodelay

The nodelay routine is used to set blocking or non-blocking read.

Syntax

   #include <curses.h>



   int nodelay(WINDOW *win, bool bf);

Parameters

bf: A Boolean expression.
win: A pointer to the window in which to enable non-blocking.

Return Values

OK: Successful completion.
ERR: An error occurred.

Description

If enabled (bf is TRUE), nodelay() causes getch() to return ERR if no input is ready. When disabled, getch() blocks until a key is pressed.




	NOTE: The `nodelay()` routine is a macro.
