3/26/2014

This method sets the IQualityControl object that will receive quality messages.

Syntax

HRESULT SetSink(
  IQualityControl* piqc
);

Parameters

  • piqc
    [in] Pointer to the IQualityControl object to which the notifications should be sent.

Return Value

Returns an HRESULT value that depends on the implementation.

HRESULT can be one of the following standard constants, or other values not listed.

Value

Description

E_FAIL

Failure.

E_POINTER

Null pointer argument.

E_INVALIDARG

Invalid argument.

E_NOTIMPL

Method is not supported.

S_OK or NOERROR

Success.

Remarks

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.
