RpcEpUnregister function (rpcdce.h)

The RpcEpUnregister function removes server-address information from the local endpoint-map database.

Syntax

RPC_STATUS RpcEpUnregister(
  RPC_IF_HANDLE      IfSpec,
  RPC_BINDING_VECTOR *BindingVector,
  UUID_VECTOR        *UuidVector
);

Parameters

IfSpec

Interface to unregister from the local endpoint-map database.

BindingVector

Pointer to a vector of binding handles to unregister.

UuidVector

Pointer to an optional vector of object UUIDs to unregister. The server application constructs this vector. RpcEpUnregister unregisters all endpoint-map database elements that match the specified IfSpec and BindingVector parameters and the object UUID(s).

A null parameter value indicates there are no object UUIDs to unregister.

Return value

Value Meaning
RPC_S_OK
The call succeeded.
RPC_S_NO_BINDINGS
No bindings.
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.
 
Note  For a list of valid error codes, see RPC Return Values.
 

Remarks

The RpcEpUnregister function removes elements from the local host's endpoint-map database. A server application calls this function only when the server has previously registered endpoints and the server wants to remove that address information from the endpoint-map database.

Specifically, RpcEpUnregister allows a server application to remove its own endpoint-map database elements (server-address information) based on the interface specification or on both the interface specification and the object UUID(s) of the resource(s) offered.

The server calls the RpcServerInqBindings function to obtain the required BindingVector parameter. To unregister selected endpoints, the server can prune the binding vector prior to calling this function.

RpcEpUnregister creates a cross-product from the IfSpec, BindingVector, and UuidVector parameters and removes each element in the cross-product from the endpoint-map database.
