Is it possible to declare empty pointer variable inside

These are sometimes required while using Win32 - Windows
Operating System API.
* Empty pointer variables are used by functions to return
information after the function is done.
My own horrible **suggestion** of empty pointer declaration
inside
function call:
`someFunction(uint & passingEmptyVariableForWrite);`
What it would do:
* A new variable is declared inside function call.
* Address of that variable is passed to the function.
* After function is done, you can refer to it for returned
value.
What's wrong with:
uint* result;
someFunction(&result);
// use *result
?

Nothing wrong. It would be just a more concise compact way to do
the same.
Also I mostly wanted to know if something like that is already
possible in D language.
It's not a huge loss if it is not possible.
