IHttpContext::IndicateCompletion Method

IIS 7.0

Indicates the completion of asynchronous work and requests that IIS resume execution on the calling thread.

virtual VOID IndicateCompletion(
) = 0;


[IN] The notification status of the asyncronous operation.

An HTTP module can use the IndicateCompletion method to indicate that an asynchronous operation has completed and request that IIS resume processing on the calling thread. This behavior is unlike the behavior of the PostCompletion method, which queues the execution to the thread pool.

If the status that is specified by the notificationStatus parameter is not REQUEST_NOTIFICATION_PENDING, the request state computer will continue without reentering the original notification entry point.


The following code example demonstrates how to create an HTTP module that uses the IndicateCompletion method to indicate that an asynchronous operation has completed.

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
