IHttpContext::PostCompletion Method

IIS 7.0

Indicates the completion of asynchronous work and requests that IIS queue execution to the thread pool.

virtual HRESULT PostCompletion(
   IN DWORD cbBytes
) = 0;

cbBytes

[IN] A DWORD that contains the number of bytes for the completion.

An HRESULT. Possible values include, but are not limited to, those in the following table.

Value

Description

S_OK

Indicates that the operation was successful.

An HTTP module can use the PostCompletion method to indicate that an asynchronous operation has completed and request that IIS resume processing. The entry point for the original notification will be reentered to allow the notification to capture the completion and return the appropriate notification status. IIS queues the execution to the thread pool, and execution will occur on a thread from the thread pool. This behavior is unlike the behavior of the IndicateCompletion method, which continues on the current thread.
