IOSurface is an object encompassing a kernel-managed rectangular pixel buffer in the IOSurface framework. It is a thin wrapper on top of an IOSurfaceClient object which actually interfaces with the kernel.
Converting IOSurfaces into normal images
| Signature | CGImageRef UICreateCGImageFromIOSurface(IOSurfaceRef ioSurface); |
