/***********************************************************************
|
||||
* CoGetStandardMarshal [OLE32.@]
|
||||
*
|
||||
* When the COM library in the client process receives a marshalled
|
||||
* interface pointer, it looks for a CLSID to be used in creating a proxy
|
||||
* for the purposes of unmarshalling the packet. If the packet does not
|
||||
* contain a CLSID for the proxy, COM calls CoGetStandardMarshal, passing a
|
||||
* NULL pUnk value.
|
||||
* This function creates a standard proxy in the client process and returns
|
||||
* a pointer to that proxy's implementation of IMarshal.
|
||||
* COM uses this pointer to call CoUnmarshalInterface to retrieve the pointer
|
||||
* to the requested interface.
|
||||
* Gets or creates a standard marshal object.
|
||||
*
|
||||
* PARAMS
|
||||
* riid [I] Interface identifier of the pUnk object.
|
||||
* pUnk [I] Optional. Object to get the marshal object for.
|
||||
* dwDestContext [I] Destination. Used to enable or disable optimizations.
|
||||
* pvDestContext [I] Reserved. Must be NULL.
|
||||
* mshlflags [I] Flags affecting the marshaling process.
|
||||
* ppMarshal [O] Address where marshal object will be stored.
|
||||
*
|
||||
* RETURNS
|
||||
* Success: S_OK.
|
||||
* Failure: HRESULT code.
|
||||
*
|
||||
* NOTES
|
||||
*
|
||||
* The function retrieves the IMarshal object associated with an object if
|
||||
* that object is currently an active stub, otherwise a new marshal object is
|
||||
* created.
