Setting a variable equal to the parent of a function?

[RedTheGreen]

Say I have a struct.

struct surface
{
    ...
    void AddToQueue();
};

So I have a global array of this struct.
surface drawing_queue[1000];
Here is the function from the struct:

void surface::AddToQueue()
{
    drawing_queue[4] = ???;
}

What would I put for "???" to set drawing_queue[4] equivalent to the parent surface (of the function that is called)?

In other words, if I call:

surface surface_to_add;
surface_to_add.AddToQueue();

What would I do to the function that would make it so that drawing_queue[4] is pointing to surface_to_add?

It looks like you want an array of pointers.
surface* drawing_queue[1000];

I think this is what you want.

void surface::AddToQueue()
{
    drawing_queue[4] = this;
}

Yeah. That would be better.

Thanks! I just haven't done this kind of thing before.
