RpcRevertToSelfEx function

The RpcRevertToSelfEx function allows a server to impersonate a client and then revert in a multithreaded operation where the call to impersonate a client can come from a thread other than the thread originally dispatched from the RPC.

Syntax

RPC_STATUS RPC_ENTRY RpcRevertToSelfEx(
   RPC_BINDING_HANDLE BindingHandle
);

Parameters

BindingHandle

Binding handle on the server that represents a binding to the client that the server impersonated. A value of zero specifies the client handle of the current thread; in this case, the functionality of RpcRevertToSelfEx is identical to that of the RpcRevertToSelf function.

Return value

Remarks

After calling RpcImpersonateClient and completing any tasks that require client impersonation, the server calls RpcRevertToSelfEx to end impersonation and to reestablish its own security identity. For example, consider a primary thread, called thread1, which is dispatched from a remote client and wakes up a worker thread, called thread2. If thread2 requires that the server impersonate the client, the server calls RpcImpersonateClient(THREAD1_CALL_HANDLE), performs the required task, calls RpcRevertToSelfEx(THREAD1_CALL_HANDLE) to end the impersonation, and then wakes up thread1.
