IViewRowset::GetSpecification

Returns the object from which the view was created.

HRESULT GetSpecification (
   REFIID        riid,
   IUnknown **   ppObject);

Parameters

riid

[in]
The IID of the interface to be returned. This interface is conceptually added to the list of required interfaces on the resulting rowset, and the method fails (E_NOINTERFACE) if that interface cannot be supported on the resulting rowset.

ppObject

[out]
A pointer to memory in which to return the interface pointer. If IViewRowset::GetSpecification fails, it must attempt to set *ppObject to a null pointer.

Return Code

S_OK

The method succeeded.

E_FAIL

A provider-specific error occurred.

E_NOINTERFACE

The view did not support the interface specified in riid.

E_OUTOFMEMORY

The provider was unable to allocate sufficient memory in which to return the object information.

Comments

IViewRowset::GetSpecification adds a reference count to the object. The consumer must call Release to release the reference count when it is no longer needed.
