The Component Manager includes these new functions: GetComponentTypeModSeed , OpenAComponent , OpenADefaultComponent, OpenAComponentResFile, and CallComponentFunctionWithStorageProcInfo . The GetComponentTypeModSeed function is similar to the GetComponentListModSeed function. The OpenAComponent , OpenADefaultComponent and OpenAComponentResFile functions expand upon existing Component Manager routines by adding an error return value. The CallComponentFunctionWithStorageProcInfo function is used for PowerPC-native component dispatching.
