IMSVidDevice::get_ClassID
This topic applies to Windows XP or later.
The get_ClassID method retrieves the device's class identifier (CLSID) as a BSTR.
Syntax
HRESULT get_ClassID( BSTR* Clsid );
Parameters
pClsid
[out] Pointer to a variable that receives a string representation of the CLSID.
Return Values
Returns an HRESULT value. Possible values include the following.
| Value | Description |
| S_OK | Success. |
| E_POINTER | NULL pointer argument. |
Remarks
This method is provided for Automation clients. C++ applications can use the IMSVidDevice::get__ClassID method, which returns a GUID rather than a BSTR.
The caller must free the returned string, using the SysFreeString function.
