HRESULT CreateInstance( LPUNKNOWN pUnkOuter, REFIID riid, void** ppvObj );
Return Value
A standard HRESULT value.
Parameters
pUnkOuter
[in] If the object is being created as part of an aggregate, then pUnkOuter must be the outer unknown. Otherwise, pUnkOuter must be NULL.
riid
[in] The IID of the requested interface. If pUnkOuter is non-NULL, riid must be IID_IUnknown.
ppvObj
[out] A pointer to the interface pointer identified by riid. If the object does not support this interface, ppvObj is set to NULL.
Remarks
Creates an object of the specified CLSID and retrieves an interface pointer to this object. If your module derives from CComAutoThreadModule, CreateInstance first selects a thread to create the object in the associated apartment.
