IWMSOutgoingDistributionConnection::get_Port

IWMSOutgoingDistributionConnection::get_Port

The get_Port method retrieves the port number of the client receiving the distributed content.

Syntax

  HRESULT get_Port(
  long*  pVal
);

Parameters

pVal

[out] Pointer to a long that contains the port number.

Return Values

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

Remarks

The port number is returned by the socket on the Windows Media server. Therefore, the port can be that of the server receiving the content, but it can also be the port number of the firewall, the network address translator, or the router, if these are in the network path.

Example Code

#include <windows.h>
#include <atlbase.h>    // Includes CComVariant.
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer                          *pServer;
IWMSOutgoingDistributionConnections *pConnections;
IWMSOutgoingDistributionConnection  *pConnection;

HRESULT         hr;
CComVariant     varIndex;
long            lCount;
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 collection of distribution
// connections and retrieve the total count of connections.
hr = pServer->get_OutgoingDistributionConnections(&pConnections);
if (FAILED(hr)) goto EXIT;
hr = pConnections->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;

// Retrieve information about each distribution connection.
for (long x = 0; x < lCount; x++)
{
    varIndex = x;
    hr = pConnections->get_Item(varIndex, &pConnection);
    if (FAILED(hr)) goto EXIT;

    // Retrieve the port of the client.
    hr = pConnection->get_Port(&lValue);
    if (FAILED(hr)) goto EXIT;

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

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