Hi.
Recently I discovered that Delphi can detect [Ctrl]+C keys using the
EControlC exception. I was curious so I decided to test it in Linux
using Free Pascal. The program I wrote:
_________________________________
PROGRAM ExControlC;
(* How to capture [Ctrl+C] in Object Pascal. *)
{$mode objfpc}{$H+}
USES
SysUtils;
VAR
Tmp: STRING;
BEGIN
TRY
WriteLN ('Press [Enter] or [Ctrl+C].');
ReadLN (Tmp);
WriteLN ('You pressed [Enter].');
EXCEPT
ON EControlC DO WriteLN ('You pressed [Ctrl+C].');
END;
WriteLN ('Have a nice day.');
END.
_________________________________
That's simple. I tested it on Linux but it doesn't worked. It compiles
and run, but if you press [Ctrl]+C the program exits without the "You
pressed [Ctrl+C]." message. Is it an issue or a bug? May be it's not
possible to detect [Ctrl]+C in Linux?
