How to receive information about pressing/releasing a key on the
keyboard in Haiku OS? My code is:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i type 
{$PACKRECORDS C}  TRawKeyInfo = record    TimeStamp : Int64;   
KeyCode   : DWord;    IsKeyDown : Boolean;  end; const  KB_READ =
9999; var  fd:LongInt;  S:TRawKeyInfo;begin 
fd:=fpopen('/dev/input/keyboard/at/0',O_RDWR);  if fd>=0 then  repeat 
  if LnxIoCtl(fd,KB_READ,@S)=0 then      WriteLn(S.TimeStamp,'
',S.IsKeyDown,' ',S.KeyCode)  until False;end.My code is not working.
What am I doing wrong?

Do you need to use it in console mode? If no, that can be done easily
using Lazarus. Here has a demo:
