I have searched the WINE code base for explicit calls to this function and have found none.  So these are my questions...

No, that's internal interface and can't be called by windows programs. However you were looking for the wrong thing. This is a COM object method, so you need to be looking for that object's call. In C that means you need to look for IWineD3DVolume_UnlockBox() function calls.

It seems you don't really understand how COM object's methods are called in C. Look at all the COM method wrappers in header files.

Also don't forget there are lots of things going on behind the scene then meets the eye. Wine doesn't just translate some "d3d function call" into "OpenGL call". It doesn't work that way.
