Abstract: A system and method for accessing virtual functions from classes compiled with compilers using different virtual function table layouts and/or different function member call protocols. A hybrid virtual function table, incorporating entries created by both legacy and adjustor thunk methods, is disclosed. The hybrid virtual function table permits backwards compatibility with previously compiled classes, while taking advantage of the faster adjustor thunk implementation for new code.
