Remarks

The RpcNsGroupMbrInqBegin function creates an inquiry context for viewing the members of an RPC group. Before calling RpcNsGroupMbrInqNext, the application must first call RpcNsGroupMbrInqBegin to create an inquiry context. When finished viewing the RPC group members, the application calls RpcNsGroupMbrInqDone to delete the inquiry context.

Note Windows 2000 Active Directory supports this function. Earlier versions of Windows NT support the use of this function with Cell Directory Service (CDS) only.

Note

The rpcnsi.h header defines RpcNsGroupMbrInqBegin as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
