The GetSubObject method retrieves the subobject associated with this object.
HRESULT GetSubObject( IUnknown **pVal );
[out, retval] Address of a pointer that receives the subobject's IUnknown interface. If the object does not have a subobject, the value is set to NULL.
Returns S_OK if successful, or E_POINTER otherwise.
Every timeline object can hold a pointer to an associated subobject.
If the value returned in pVal is not NULL, the IUnknown interface has an outstanding reference count. Be sure to release the interface when you are finished using it.
