The UnmapStreamId method unmaps the Stream ID mapping created in a previous call to MapStreamId.
Syntax
HRESULT UnmapStreamId(
ULONG culStreamId,
ULONG* pulStreamID
);
Parameters
culStreamId
[in] Variable of type ULONG that specifies the number of elements in the pulStreamID array.
pulStreamID
[in] Array of Stream IDs mapped for this pin.
Return Value
Returns S_OK if successful. If the method fails, it returns an HRESULT error code.
Remarks
There is typically only one stream ID mapped to a given pin, therefore pulStreamID will typically contain a single element.
