RpcNsBindingExportPnPW function (rpcnsi.h)

The RpcNsBindingExportPnP function establishes a name-service database entry with multiple binding handles and multiple objects for a server that supports Plug and Play.

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

 

Syntax

RPC_STATUS RpcNsBindingExportPnPW(
  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 to which binding handles and object UUIDs are exported. You cannot provide a null or empty string.

To use the entry name specified in the registry value entry HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\NameService\DefaultEntry, provide a null pointer or an empty string. In this case, the EntryNameSyntax parameter is ignored and the run-time library uses the default syntax.

IfSpec

Stub-generated data structure specifying the interface to export. A null value indicates there are no binding handles to export (only object UUIDs are to be exported) and BindingVec is ignored.

ObjectVector

Pointer to a vector of object UUIDs offered by the server. The server application constructs this vector. A null value indicates there are no object UUIDs to export (only binding handles are to be exported).

Return value

Value	Meaning
RPC_S_OK	The call succeeded.
RPC_S_NOTHING_TO_EXPORT	There was nothing to export.
RPC_S_INVALID_BINDING	The binding handle was invalid.
RPC_S_WRONG_KIND_OF_BINDING	This was the wrong kind of binding for the operation.
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_NO_NS_PRIVILEGE	No privilege for name-service operation.
RPC_S_NAME_SERVICE_UNAVAILABLE	The name service is unavailable.

Remarks

The RpcNsBindingExportPnP function allows a server application to publicly offer an interface in the name-service database that supports Plug and Play bindings for use by any client application.

Note that the server application should not explicitly supply the binding vector when exporting Plug and Play bindings. The bindings are automatically updated when there is a change in the bindings due to a Plug and Play event.

Note

The rpcnsi.h header defines RpcNsBindingExportPnP 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.
