# IUnknown

[IUnknown](/windows/win32/api/unknwn/nn-unknwn-iunknown) is the base interface of every other COM interface. This interface defines three methods: [QueryInterface](/windows/win32/api/unknwn/nf-unknwn-iunknown-queryinterface(q_)), [AddRef](/windows/win32/api/unknwn/nf-unknwn-iunknown-addref), and [Release](/windows/win32/api/unknwn/nf-unknwn-iunknown-release). [QueryInterface](/windows/win32/api/unknwn/nf-unknwn-iunknown-queryinterface(q_)) allows an interface user to ask the object for a pointer to another of its interfaces. [AddRef](/windows/win32/api/unknwn/nf-unknwn-iunknown-addref) and [Release](/windows/win32/api/unknwn/nf-unknwn-iunknown-release) implement reference counting on the interface.

# QueryInterface

Although there are mechanisms by which an object can express the functionality it provides statically (before it is instantiated), the fundamental COM mechanism is to use the `IUnknown` method called [QueryInterface](/windows/win32/api/unknwn/nf-unknwn-iunknown-queryinterface(q_)).
Although there are mechanisms by which an object can express the functionality it provides statically (before it is instantiated), the fundamental COM mechanism is to use the `IUnknown` method called [QueryInterface](/windows/win32/api/unknwn/nf-unknwn-iunknown-queryinterface(q)).

Every interface is derived from `IUnknown`, so every interface has an implementation of `QueryInterface`. Regardless of implementation, this method queries an object using the IID of the interface to which the caller wants a pointer. If the object supports that interface, `QueryInterface` retrieves a pointer to the interface, while also calling `AddRef`. Otherwise, it returns the E_NOINTERFACE error code.
