HRESULT GetDBSession (
REFIID riid,
IUnknown ** ppSession);
Parameters
riid
[in]
The IID of the interface on which to return a pointer.
ppSession
[out]
A pointer to memory in which to return the interface pointer. If the provider does not have an object that created the command, it sets *ppSession to a null pointer. If GetDBSession fails, it must attempt to set *ppSession to a null pointer.
Return Code
S_OK
The method succeeded.
S_FALSE
The provider did not have an object that created the command. Therefore, it set *ppSession to a null pointer.
E_FAIL
A provider-specific error occurred.
E_INVALIDARG
ppSession was a null pointer.
E_NOINTERFACE
The session did not support the interface specified in riid.
