Passed by reference this would render an address, which on a 32-bit platform will usually come through successfully as a 32-bit numeric.

I thik I've used "L" to pass pointers — specifically, for nullable pointers — but I didn't use hardcoded address 123456789 or '    '. (Is that a weird way of saying NULL?)

I'd assume that the String type mentioned is a the VB type String.

He said the function is written in C++, I figured it was C++'s String. He really is being unclear if he can't even communicate which language's class he's talking about.

But even if he were to communicate which class he's using clearly, it doesn't say anything about the structure of the type, necessary knowledge for building an instance of one.
