It doesn't hold any special meaning in Visual C++ that it doesn't hold in C++. this
is a pointer to the object for which a member function is invoked.
If you have some object of type IUnknown object
then when QueryInterface
is invoked for object
, the use of this
inside the method implementation resolves to the address of object
