This topic provides information about implementing CreateCAnimDllL(). 
Use CreateCAnimDllL() to construct
the CAnimDll derived server side DLL class. For
example, for a DLL class called CExampleAnimDll the
following code would appear in the DLL source file: 
// the only exported function in the DLL
IMPORT_C CAnimDll* CreateCAnimDllL();
EXPORT_C CAnimDll* CreateCAnimDllL(){return new(ELeave) CExampleAnimDll;}
The use of both IMPORT_C and EXPORT_C statements is required to satisfy different compiler conventions.
Because this interface is defined by the Window Server, an animation
DLL class must be linked against the Window Server definitions, otherwise
linkage will fail. The mechanism is straightforward — include the
following in your project mmp file:
