The server calls RpcServerTestCancel to test for client cancel requests.
#include <rpc.h>
RPC_STATUS RPC_ENTRY RpcServerTestCancel(
RPC_BINDING_HANDLE BindingHandle
);
| Value | Meaning |
|---|---|
| RPC_S_OK | The call was canceled. |
| RPC_S_NO_CALL_ACTIVE | There is no active call on the current thread. |
| RPC_S_CALL_IN_PROGRESS | The call was not canceled. |
| RPC_S_INVALID_BINDING | The handle is not valid. |
The server calls RpcServerTestCancel to find out if the client has requested cancellation of an outstanding call. The Binding Handle parameter specifies the call on which to test. If the parameter has a value of zero, the call on the current thread is tested. The server can call RpcServerTestCancel(RpcAsyncGetCallHandle(pAsync)) to test for cancels using the asynchronous handle to obtain the binding handle.
