Enumerating Direct3D Devices

The first thing a Direct3D application should do is enumerate the available Direct3D device drivers. The most important API element in this job is IDirect3D2::EnumDevices.

This section contains the ChooseDevice function that selects among the available Direct3D devices and the EnumDeviceCallback function that implements the selection mechanism.
