Mechanics of C++ Virtual Dispatch and Vtable Layout

Runtime Polymorphism Foundation Virtual member funcsions enable dynamic dispatch by deferring method resolution until execution time. Instead of relying on the declared type, the compiler routes invocations through a per-class lookup structure known as the virtual table. This arrangement allows deri...

Understanding C++ Virtual Tables and VTable Hooking

Exploring Virtual Tables (VTables) To understand the lifecycle and structure of virtual tables in C++, let's start with a set of test classes involving virtual functions and multiple inheritance. Virtual Function Classes #include <cstdio> class SampleClass { public: int internalValue; virtual...
