The simple solution is to do a cast and pass it as an Integer. Just leave
the typelib alone and pass an Integer parameter which is actually the
address of the record/structure.
I have done this before - works fine. Can even pass object references this
way - I find this better, because you can then do a runtime type check using
the IS operator.
I would suggest the callee do as type check just to make sure the passed
Integer is valid. This is easier todo with
eg PassRecord( Integer( @MyRecord ))
or PassObjectReference( Integer( @MyObject ));
procedure PassObjectReference( Value: Integer );
...
if (Value is TMyObject) then ....
