Parameters
- riid
- [in] The IID of the interface on which to return a pointer.

- [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.
