Sample C code for Canon EDSDK Liveview?

Is there anyone with a working piece of sample C code that implements LiveView using the Canon EDSDK? The sample code in the documentation looks great until you get to this bit:

// 
// Display image 
//

Yup, that's it. They don't show how to BLT an image to a window using the data retrieved from the camera. They just say, "Display image." Thanks, Canon.

I have hunted the Internet (including this forum), but I have yet to find a C code sample that shows how to do this. I'm looking to avoid MFC, VB, managed code, or C#. Surely it's possible to do this in vanilla C, right? Vanilla C++ is fine as well.

It is commented out probably because isplaying images is platform and hardware dependent. No one can answer your question without knowing what OS you are targeting. Besides, every major OS today runs apps as managed code. The only advantage to using C/C++ is you may wind up with more compact code.

[EDIT]. BTW, this is not a developer's forum. The "Software" label refers to user applications.
