Returning a struct by value means that a function generates a copy of the entire struct and passes it back to the caller. This approach is straightforward and effective for small or moderately sized structs. In the example below, the functionreturnStructByValuereturns a struct directly. This wor...
This pointer is only valid if the class supports dynamic creation; otherwise, the function returns NULL. CRuntimeClass::m_pfnGetBaseClass If your application uses the MFC library as a shared DLL, this data member points to a function that returns theCRuntimeClassstructure of the base class....
