The SetSink method sets the IQualityControl object that will receive quality messages.
HRESULT SetSink( IQualityControl *piqc );
Pointer to the IQualityControl object to which the notifications should be sent.
Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.
|E_POINTER||Null pointer argument.|
|E_NOTIMPL||Method isn't supported.|
|S_OK or NOERROR||Success.|
The filter that receives a call to this method should record the piqc but should not add a reference count to it. The object pointed to will be a quality manager and will be a part of the filter graph (for example, a plug-in distributor). Adding a reference count to this could cause circular reference problems.
The reference to the object specified in piqc is guaranteed to be valid until this method is called with a null value.
