Hi Guys,

I am trying to retrieve a RenderTargetView* from a class I have created, like this

ID3D11RenderTargetView* RenderTargetSelect()
{
	return renderTextureView;
}

When I try to use the pointer (as follows) I get the following error.

d3dContext->OMSetRenderTargets(1, it->RenderTargetSelect(), 0);

"ID3D11RenderTargetView *" is incompatible with parameter of type "ID3D11RenderTargetView *const *"


I tried casting it to ID3D11RenderTargetView *const * but the program just crashes. Error handling confirms that the pointer to the render target view is valid.

Not sure why this isn't compiling, so a helping hand would be greatly appreciated.

The reason that OMSetRenderTargets takes a pointer to a pointer (instead of just a pointer), is because it expects an array of pointers to render target views. This is so that you can set multiple render targets simultaneously with 1 API call. It's the same for all of the functions that set shader resource views, samplers, constant buffers, and unordered access views. I usually prefer to make an array on the stack to pass into those functions, like this:

ID3D11RenderTargetView* rtViews[] = { it->RenderTargetSelect() };
d3dContext->OMSetRenderTargets(1, rtViews, nullptr);
