IMDDataset::GetSpecification

Returns an interface pointer on the command object that created the dataset.

Syntax

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

Parameters

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

• ppSpecification
  [out] A pointer to memory in which to return the interface pointer. If the provider does not have an object that created the dataset, it sets ppSpecification to a null pointer and returns S_FALSE. If IMDDataset::GetSpecification fails, it must attempt to set ppSpecification to a null pointer.

Return Code

• S_OK
  The method succeeded.

• S_FALSE
  The provider does not have a command object that created the dataset.

• E_FAIL
  A provider-specific error occurred.

• E_INVALIDARG
  ppSpecification was a null pointer.

• E_NOINTERFACE
  The object that created this dataset did not support the interface specified in riid.
