Delphi pointer syntax

Question

I have to pass an argument of the type Pointer to a function from an external DLL.

• How do I create a pointer to a procedure which I can then pass to the function?
• Can I also pass a pointer to a class member function to the external function, or will that not work?

Answer 1

Just use @MyProcedure for that.

Beware that it has to have the right calling convention (probably stdcall).

You usually can't use a member function, because it has a hidden SELF parameter.

A class static method acts like a usual procedure/function though.
