C++ Under the Hood: Internal Class Mechanisms

by Chris Ryan

Summary of the talk:

My talk will examine the internal C++ mechanisms around the topics of:

• Order of Object construction & destruction, and pre- & post-main() processing.
• Member Function Pointers (not your father’s C function pointer),
• Member Data Pointers (not raw pointers) (data-morphic functionality),
• Understanding the Call Stack, Stack Frames and Base Pointer mechanisms.
