Creates an object in the protect media path (PMP) process, from a CLSID.

Syntax

HRESULT CreateObjectByCLSID(
  [in]   REFCLSID clsid,
  [in]   IStream *pStream,
  [in]   REFIID riid,
  [out]  void **ppv
);

Parameter

• clsid [in]
  The CLSID of the object to create.

• pStream [in]
  A pointer to the IStream interface. This parameter can be NULL. If this parameter is not NULL, the PMP host queries the created object for the IPersistStream interface and calls IPersistStream::Load, passing in the pStream pointer.

• riid [in]
  The interface identifier (IID) of the interface to retrieve.

• ppv [out]
  Receives a pointer to the requested interface. The caller must release the interface.

Rückgabewert

Ist Methode erfolgreich, wird "S_OK" zurückgegeben. Andernfalls wird ein HRESULT-Fehlercode zurückgegeben.

Hinweise

You can use the pStream parameter to initialize the object after it is created.
