Get interface pointers without using the exported CreateInterface function.

InterfaceReg.cpp

// Find the pointer to 'InterfaceReg::s_pInterfaceRegs' - works on Valve game libraries. (32-bit)
uintptr_t interface_list_addr = FindPattern("bin/client.so", "89 10 8B 15 ? ? ? ? A3") + 4;
InterfaceReg* interface_list = **reinterpret_cast<InterfaceReg***>(interface_list_addr);

for (InterfaceReg* current = interface_list; current; current = current->m_pNext) {
	printf("* %s => 0x%x\n", current->m_pName, current->m_CreateFn());
}

InterfaceReg.h
