Value	Meaning

Remarks

The RpcNsGroupMbrAdd adds a name service–database entry name as a member to the RPC group attribute.

If the GroupName entry does not exist, RpcNsGroupMbrAdd tries to create the entry with a group attribute and adds the group member specified by MemberName. In this case, the application must have the privilege to create the entry. Otherwise, a management application with the necessary privilege should create the entry by calling RpcNsMgmtEntryCreate before the application is run.

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 RpcNsGroupMbrAdd 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. For more information, see Conventions for Function Prototypes.
