GetPrivateData is not the call you're looking for - it's not used for this kind of operation at all. Depending on the buffer's usage and CPU access flags, you can use one of Map or CopyResource to do this.
It appears that the gentleman thought C++ was extremely difficult and he was overjoyed that the machine was absorbing it; he understood that good C++ is difficult but the best C++ is well-nigh unintelligible.

Basically, Get/Set PrivateData is so you can associate application-specific data to the object, e.g. set a "friendly" name to it for debugging purposes.
