CLoadDirectDraw Class (Compact 2013)

3/26/2014

CLoadDirectDraw Class

DirectShow must work on multiple platforms. The filters therefore cannot link statically to the Microsoft DirectDraw® library.

To make the platform dependencies easier to handle, this class manages loading and unloading the library and creating the initial IDirectDraw interface.
