IFilterMapper::RegisterFilterInstance (Windows Embedded CE 6.0)
1/6/2010
This method registers an identifiable instance of a filter.
Syntax
HRESULT RegisterFilterInstance(
CLSID clsid,
LPCWSTR Name,
CLSID* MRId
);
Parameters
- clsid
[in] Globally unique identifier (GUID) of the filter.
- Name
[in] Descriptive name of the instance.
- MRId
[out] Returned media resource ID. This parameter is a locally unique identifier for this instance of this filter.
Return Value
Returns an HRESULT value.
Remarks
This method handles cases such as when two similar sound cards that are driven by the same driver are available, and it is necessary to choose which card will emit the sound. This is not needed if there is only one instance of the filter (such as when there is only one sound card in the computer), or if all instances of the filter are equivalent.
The filter itself must have already been registered.
