Apple added the new IOSurface framework as part of the 10.6 Mac OS X firm update. Since this framework relatively new, I haven't found the much need documentation on how to properly use this.
I was wondering if there anyone on StackOverflow that can assist me with IOSurface usage.
Anyways, this is what I want to do. Right now my application is very simple so that I can become familiar with IOSurfaces. So essentially, I would want to load up an image into an IOSurface texture and display in a custom OpenGLView. That's all I am aiming for at this point.
To make this more simple, I just load one constant color in the IOSurface. My main objective at this point is to create an IOSurface reference and display in a custom OpenGL view.
Please help me with -IOSurface declaration statements -Loading data into the IOSurface -and the syntax for drawing the IOSurface in OpenGL.
Much appreciated.
p.s.
IOSurface is like a memory manager that passes graphic data between applications or something a long the line of that.
I have tried Google IOSurface. And the most helpful site is

However, when I tried compile the example code, I have a compiler error stating that QTVisualContextRef and other QuickTime variables undeclared. I have the latest version of Quick Time through the automatic update.
