copied!<p>You mention that you don't want to use a named pipe for internal use; it's probably worth poining out that the documentation for <a href="http://msdn.microsoft.com/en-us/library/aa365152(VS.85).aspx" rel="nofollow noreferrer">CreatePipe()</a> states, <em>"Anonymous pipes are implemented using a named pipe with a unique name. Therefore, you can often pass a handle to an anonymous pipe to a function that requires a handle to a named pipe."</em> So, I suggest that you just write a function that creates a similar pipe with the correct settings for async reading. I tend to use a GUID as a string (generated using <code>CoCreateGUID()</code> and <code>StringFromIID()</code>) to give me a unique name and then create the server and client ends of the named pipe with the correct settings for overlapped I/O (more details on this, and code, here: <a href="http://www.lenholgate.com/blog/2008/02/process-management-using-jobs-on-windows.html" rel="nofollow noreferrer">http://www.lenholgate.com/blog/2008/02/process-management-using-jobs-on-windows.html</a>).</p> <p>Once I have that I wire up some code that I have to read a file using overlapped I/O with an I/O Completion Port and, well, then I just get async notifications of the data as it arrives... However, I've got a fair amount of well tested library code in there that makes it all happen... </p> <p>It's probably possible to set up the named pipe and then just do an overlapped read with an event in your <code>OVERLAPPED</code> structure and check the event to see if data was available... I don't have any code available that does that though.</p>
