The SetObjectAttributes method specifies the file attributes. This method is currently not called by Windows Media Device Manager.
Syntax
HRESULT SetObjectAttributes(DWORDdwAttributes,_WAVEFORMATEX*pFormat);
Parameters
dwAttributes
[in] DWORD specifying the object attributes as defined in the IWMDMStorage::SetAttributes method.
pFormat
[in] Pointer to a _WAVEFORMATEX structure specifying the format for files with audio data attributes. If the file contains audio data, this parameter should be filled.
Return Values
The application should return one of the following HRESULT values.
| Return code | Description |
| S_OK | The read operation should continue. |
| WMDM_E_USER_CANCELLED | The read operation should be cancelled without finishing. |
| E_FAIL | An unspecified error occurred, and the read operation should be cancelled without finishing. |
If the application returns either E_FAIL or WMDM_E_USER_CANCELLED, the operation is terminated and the End method is called. If the application is using block mode and returns WMDM_E_USER_CANCELLED, then Windows Media Device Manager will return that error to the application.
