RpcNsBindingUnexportPnPW function (rpcnsi.h)

The RpcNsBindingUnexportPnP function removes the binding handles for Plug and Play interfaces and objects from an entry in the name-service database.

Note  This function is not supported on Windows Vista and later operating systems.

 

Syntax

RPC_STATUS RpcNsBindingUnexportPnPW(
  unsigned long EntryNameSyntax,
  RPC_WSTR      EntryName,
  RPC_IF_HANDLE IfSpec,
  UUID_VECTOR   *ObjectVector
);

Parameters

EntryNameSyntax

Syntax of EntryName.

To use the syntax specified in the registry value entry HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\NameService\DefaultSyntax, provide a value of RPC_C_NS_SYNTAX_DEFAULT.

EntryName

Pointer to the entry name from which to remove binding handles and object UUIDs.

IfSpec

Interface specification for the binding handles to be removed from the name service database. A null parameter value indicates not to unexport any binding handles (only object UUIDs are to be unexported).

ObjectVector

Pointer to a vector of object UUIDs that the server no longer wants to offer. The application constructs this vector. A null value indicates there are no object UUIDs to unexport (only binding handles are to be unexported).

Return value

Value	Meaning
RPC_S_OK	The call succeeded.
RPC_S_INVALID_VERS_OPTION	The version option is invalid.
RPC_S_INVALID_NAME_SYNTAX	The name syntax is invalid.
RPC_S_UNSUPPORTED_NAME_SYNTAX	The name syntax is unsupported.
RPC_S_INCOMPLETE_NAME	The name is incomplete.
RPC_S_ENTRY_NOT_FOUND	The name-service entry was not found.

Remarks

The RpcNsBindingUnexportPnP function allows a server application to remove the binding handles and object UUIDs of Plug and Play-compatible resources from a name service database entry. A server application can unexport the specified interface and objects in a single call to RpcNsBindingUnexportPnP, or it can unexport them separately. Only the binding handles that match the interface UUID and the major and minor interface version numbers found in the IfSpec parameter are unexported.

Note

The rpcnsi.h header defines RpcNsBindingUnexportPnP as an alias that 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 is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
