The RpcCancelThread function cancels a thread. The RpcCancelThread function should not be used to cancel asynchronous RPC calls; instead, use the RpcAsyncCancelCall function to cancel an asynchronous RPC call.
Handle of the thread to cancel.
| Value | Meaning |
|---|---|
|
The call succeeded. |
|
Thread handle does not have privilege. Thread handles must have THREAD_SET_CONTEXT set properly for the function to execute properly. |
|
Called by an MS-DOS or Windows 3.x client. |
The RpcCancelThread function allows one client thread to cancel an RPC in progress on another client thread. When the function is called, the server run-time is informed of the cancel operation. The server stub can determine if the call has been canceled by calling RpcTestCancel. If the call has been canceled, the server stub should clean up and return control to the client.
The RpcCancelThread function cannot be used to cancel a call that has issued a static callback. Do not cancel remote procedure calls that may call a function declared with the [callback] attribute in the IDL-file.
By default, the client waits forever for the server to return control after a cancel. To reduce this time, call RpcMgmtSetCancelTimeout, specifying the number of seconds to wait for a response. If the server does not return within this interval, the call fails at the client with an RPC_S_CALL_FAILED exception. The server stub continues to run.
If you are using the named pipes protocol, ncacn_np, you must specify a finite time-out.
You can use RpcCancelThread with any of the connection-oriented protocols (ncacn_*) and with any of the datagram protocols except ncadg_mq and ncalrpc.
Note Windows XP/2000 The RpcCancelThread function is not available for ncacn_http. The RpcCancelThread function supports ncacn_http on Windows Server 2003 or later operating systems and Windows XP with Service Pack 1 (SP1) and later.
