I'm trying to pass a pointer value to Delphi, but it seems that DBPro can only pass variable types. I need to do something like this...

function PtrTest(temp: integer): integer; cdecl;
var
ptr: PInt;
begin
ptr := temp;
end;

But it won't let me due to incompatable types. Is there any way of passing an address straight into a pointer like so...

function PtrTest(ptr: PInt): integer; cdecl;
begin
end;

Or any way of assigning a variable's value to the pointer address, like the above example.

Cheers.

Isn't it? Wasn't it? Marvellous!

Feck it, I just found out you can pass pointers as if there are integers.

Yep, pointers are just dwords. Or Uint. Don't use Integer as some compilers will mess ur stuff up. Not that the cpu cares though.
