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.
