How do I flush the keyboard input buffer?

All I need is to simply flush out the keyboard buffer, but I can't seem
to find the function or anything dealing with it?
Can anybody help.

This is Windows...you can't flush the keyboard. Your program gets input from a
message queque, not the hardware and Windows handles the hardware without your
involvement--why do you need to flush the keyboard?

Look up PeekMessage in the help file. Maybe that will help.

Hi,

Use this code to flush the keyboard buffer .in the past , it was not
easy for me to know it.

procedure clearkbrdbuf;
var
keybuf_head:byte absolute $0040:$001A;
keybuf_tail:byte absolute $0040:$001C;
begin
keybuf_head:=$1E;
keybuf_tail:=$1E;
end;
