I'm creating a class out of a C header converted to pascal using h2pas.

I created this type:

pRobotArray = ^TArray0toMAX_ROBOT_DRIVES1OfHANDLE;

If I use it inside a method, like this:

procedure TMyClass.myMethod;
var
   lRobots: pRobotArray;
begin
   getRobots(lHRobots);
   lRobots := @lHRobots; // this works ok.
end;

If I add an FRobots var to my class:

TRobotClass = class
private
   FRobots: pRobotArray;
public
   procedure myMethod;
end;
procedure TMyClass.myMethod;
begin
   getRobots(lHRobots);
   FRobots := @lHRobots; // I get an external SIGSEGV.
end;

Why the difference?.

Regards,

No, lHRobots is not defined.

Please provide a complete example.

Please, forget about this. I was using a header for a different version of the dll.
