IWMSPlayer::get_WrapperPlaylist

The get_Playlist method retrieves a wrapper playlist object.

Syntax

  HRESULT get_WrapperPlaylist(
  IWMSPlaylist**  pVal
);

Parameters

pVal

[out] Pointer to a pointer to an IWMSPlaylist interface. This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.

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

You can use the IWMSPublishingPoint::get_WrapperPath method to retrieve the path to the playlist file.

Example Code

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

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSPlayers     *pPlayers;
IWMSPlayer      *pPlayer;
IWMSPlaylist    *pPlaylist;

HRESULT         hr;
CComVariant     varIndex;
long            lCount;

// 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 wrapper playlist used by the client
    // if one exists.
    hr = pPlayer->get_WrapperPlaylist(&pPlaylist);
    if (FAILED(hr)) goto EXIT;

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

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