all referencing, no pointers

[kryton9]

I thought this should work from what I read, but I get errors.

How would the proper conversion be done, I am stuck after trying many combinations. I just posted this test, as to the best of my understanding it should work?

Code: Select all

IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9,dimension2d<s32>(1024, 768),32,true,false,false);
IrrlichtDevice win = (*device);
IVideoDriver* driver = win.getVideoDriver();

Thanks for any enlightenment.

Why would you want to convert a pointer to a reference, especially like that?

Code: Select all

IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9,dimension2d<s32>(1024, 768),32,true,false,false);
IrrlichtDevice win = (*device);

The code you post is not using a reference. You are attempting to copy an IrrlichtDevice, which, if I'm remembering correctly, is an abstract class and thus cannot be copied in this way.

If you want a reference, you need to tell the compiler that...

Code: Select all

IrrlichtDevice* device_ptr = ...;
IrrlichtDevice& device_ref = *device_ptr;

I don't really understand why you'd want to do this though. It doesn't buy you much of anything. All it does is guarantee that device_ref refers to a non-null object and you get to use the . operator instead of ->.

looks to me like he wants to create a different reference for each OS.

win + directx9 = my assumption.

and yeah I really don't understand what he is going for exactly. looks like something that would require specification and a c++ forum.

@vitek Thanks. I asked, one to learn and understand after trying everything I could find on the subject from many hours of tinkering.

I have seen libraries that don't have -> and have the . notation and wondered how they pulled it off. DirectX uses pointers and I always wondered how those library writers could write the code.

Thanks again, I will do a search for that syntax to see why I hadn't run across information as valuable as that.

@Midnight and @DtD I can understand why you would wonder why I would ask such a question, but this really helped me tonight.
