IVdsSubSystem2::GetProperties2 method (vdshwprv.h)
Returns the properties of a subsystem. This method is identical to the IVdsSubSystem::GetProperties method, except that it returns a VDS_SUB_SYSTEM_PROP2 structure instead of a VDS_SUB_SYSTEM_PROP structure.
HRESULT GetProperties2( [out] VDS_SUB_SYSTEM_PROP2 *pSubSystemProp2 );
The address of the VDS_SUB_SYSTEM_PROP2 structure allocated and passed in by the caller. VDS allocates memory for the pwszFriendlyName and pwszIdentification member strings. Callers must free the strings by using the CoTaskMemFree function.
This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.
||Some but not all of the properties were successfully retrieved. Note that there are many possible reasons for failing to retrieve all properties, including device removal.|
||There is a software or communication problem inside a provider that caches information about the array. Use the IVdsHwProvider::Reenumerate method followed by the IVdsHwProvider::Refresh method to restore the cache.|
||The subsystem object is no longer present.|
