IWMSPublishingPointPeakCounters::get_StreamingUDPPlayers

The get_StreamingUDPPlayers method retrieves the maximum number of players that have streamed content simultaneously by using the User Datagram Protocol (UDP) from the publishing point.

HRESULT get_StreamingUDPPlayers(
  long*  pVal
);

Arguments

pVal	[out] Pointer to a long containing the maximum number of players that have streamed content.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code	Number	Description
E_POINTER	0x80004003	Indicates that pVal is a NULL pointer argument.

Remarks

Clients that have stopped or paused rendering the stream are not included in the count.

You can reset the pVal parameter to the current value by calling the IWMSPublishingPointPeakCounters::Reset method.

// Declare variables and interfaces.

    // Retrieve a pointer to a list of peak statistics
    // for the publishing point.
    hr = pPubPoint->get_PeakCounters(&pPeakCounters);
    if (FAILED(hr)) goto EXIT;

    // Retrieve the maximum number of streaming players
    // since the start time.
    hr = pPeakCounters->get_StreamingUDPPlayers(&lValue);
    if (FAILED(hr)) goto EXIT;

    // Release temporary COM objects.
    pPubPoint->Release();
    pPeakCounters->Release();
}

EXIT:
