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

Parameters

riid
[in] The IID of the interface on which to return a pointer.
ppRowset
[out] A pointer to memory in which to return the interface pointer. If IViewChapter::GetSpecification fails, it must attempt to set *ppRowset 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 rowset information.

Comments

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