Yes. Yes, as long as the exception is handled (caught) by the RTL. do you mean that it cannot be a unhandled exception with ''crash'' and heaptrace dumping the thousands of left-behind memory blocks that weren't deallocated?? that's what i'm trying to get past... i want to see the error and unhandled exceptions but i really want to properly deallocate the 4+ * 5 records on the heap instead of having to either wait for heaptrace to finish dumping them or forcibly closing the task or (in the worst cases) rebooting the entire machine... this is a console app based on tapplication (mainly for parameter parsing capability) and i have no clue (yet) how to catch exceptions and deal with them properly... additionally, this last time i had to deal with this, fpc 2.6.4 release for OS/2 was dieing with unknown error 110 (IIRC) during runtime... i finally determined this to be from trying to reset a file that didn't exist where the path was pointing to... goofy error on my part that i fixed by fsplitting the pattern and adding the directory portion back to the initial directory path being used... in any case, i thought i should also mention this so that it can be corrected so it is not unknown any more ;) -- NOTE: No off-list assistance is given without prior approval.

[fpc-pascal] ExitProc
If I compile and run my example program and then press Crtl+C the
program terminates. I would expect that it terminate by calling
CloseServer procedure, but it dos not. If the program terminates
normally (time runs out) the CloseServer procedure is called as
expected.
Have I misunderstood something about the ExitProc.
Regards Carsten
program exitp;
Uses sysutils;{System}
var
ExitProcGem:pointer;
Procedure CloseServer;
Begin
ExitProc:=ExitProcGem;
WriteLn('Server closed.');
End;
begin
ExitProcGem:=ExitProc;
ExitProc:[EMAIL PROTECTED];
sleep(1);
WriteLn('--Close--');
end.

Have I misunderstood something about the ExitProc. ExitProc is only called if your program exits via the RTL. This is the case when the program exits normally, or when a run time error or unhandled exception occurs. ctrl-c is not caught by the FPC RTL. This means it is handled by the operating system, and the default action of the operating system is to simply terminate the process. The FPC RTL therefore does not get any chance to call your exitproc. I don't know whether there's a platform-independent way in the RTL to turn on the catching of ctrl-c (and converting it to an exception or run time error).

Well, unit Crt should allow it if implemented properly (i.e. compatible to TP/BP - at least IIRC)... ;-) Not that we'd have such an implementation at the moment, though.
