IWMSServerCurrentCounters::get_StreamErrorRate

The get_StreamErrorRate method retrieves the number of dropped packets per second.

HRESULT get_StreamErrorRate(
  long*  pVal
);

Arguments

pVal	[out] Pointer to a long containing the error rate in dropped packets per second.

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

The server uses a 1-second interval to calculate the rate. To calculate a more current value, use the IWMSServerTotalCounters::get_StreamErrors method.

Example

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer                  *pServer;
IWMSServerCurrentCounters   *pCurrentCounters;

HRESULT         hr;
long            lValue;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to a list of current statistics
// for the server.
hr = pServer->get_CurrentCounters(&pCurrentCounters);
if (FAILED(hr)) goto EXIT;

// Retrieve the number of dropped packets per second.
hr = pCurrentCounters->get_StreamErrorRate(&lValue);
if (FAILED(hr)) goto EXIT;

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
