4.1 RemUnknown::RemQueryInterface

QueryInterface for and return the result thereof for zero or more interfaces from the interface behind the IPID ipid. ipid must designate an interface derived from IUnknown (recall that all remoted interfaces must derive from IUnknown). The QueryInterface calls on the object that are used to service this request are conducted on the IUnknown interface of the object.

Argument	Type	Semantic
Ripid	REFIPID	The interface on an object fromwhom more interfaces are desired.
CRefs	Unsigned long	The number of references sought on each of the returned IIDs.
Ciids	Unsigned short	The interfaces being requested.
Iids	IID*	The list of IIDsthat name the interfaces sough on this object.
PpQIResults	REMQUIRESULT**	The place at which the arraay of the results of the various QueryInterface calls are returned.

ReturnValue	Meaning
S_OK	Success. An attempt was made to retrieve each of the requested interfaces from the indicated object; that is, QueryInterface was actually invoked for each IID. QueryInterface returned S_OK for every IID specified.
S_FALSE	Success. An attempt was made to retrieve each of the requested interfaces from the indicated object; that is, QueryInterface was actually invoked for each IID. QueryInterface returned a failure code for at least one of the IIDs specified.
E_NOINTERFACE	QueryInterface returned a failure code for every IID specifed.
E_INVALIDARG	One or more arguments (likely ipid) were invalid. No result values are returned.
E_UNEXPECTED	An unspecified error occurred
E_OUTOFMEMORY	Insufficient memory to complete the call.
RPC_E_INVALID_OBJECT	The requested object does not exist. No result values are returned.

4.1.1 REMQIRESULT

The REMQIRESULT structure contains the following members:

Member	Type	Semantic
HResult	HRESULT	The result code from the QueryInterface call made for the requested IID.
Std	STDOBJREF	The data for the returned interface. Note that if hResult indicates failure then the contents of STDOBJREF are undefined.
