IWMSPlayer::get_Port

The get_Port method retrieves the port number of the client that is receiving content from the server.

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.

Return code	Number	Meaning
E_POINTER	0x80004003	pVal is a NULL pointer argument.

Remarks

The network address is returned by the socket on the Windows Media server. Therefore, the address can be that of the player receiving the content, but it can also be the address 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;
IWMSPlayers     *pPlayers;
IWMSPlayer      *pPlayer;

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 an IWMSPlayers interface
// and retrieve the total count of current connections.
hr = pServer->get_Players(&pPlayers);
if (FAILED(hr)) goto EXIT;
hr = pPlayers->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;

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

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

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

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