class def

			public ref class PixelFormatDescriptor
			{
			public:
				PixelFormatDescriptor();
				PixelFormatDescriptor(PIXELFORMATDESCRIPTOR *pfd);

				const PIXELFORMATDESCRIPTOR* operator*(System::Drawing::GLSharp::PixelFormatDescriptor ^p)
				{
					return m_pfd;
				}
***

usage:

PixelFormatDescriptor ^pfd = new PixelFormatDescriptor();
::ChoosePixelFormat(m_hdc, pfd);

problem:

ChoosePixelFormat expects pfd to be a const PIXELFORMATDESCRIPTOR *, how would i fix the operator overload?
