From: "Erich E. Hoover" Subject: [PATCH 2/2] ws2_32: Use STATUS_MORE_PROCESSING_REQUIRED to indicate that the AcceptEx async should not send a completion (try 4). Message-Id: Date: Wed, 6 Jun 2012 17:53:39 -0600 Real Name: Erich Hoover Description: This patch changes the way AcceptEx handles completions so that canceled sockets can still send completion notifications. The patch fixes a significant issue with the WoW launcher and the Diablo 3 installer (Bug #28898) where these applications hang indefinitely waiting for a completion to be returned for the AcceptEx async. This version of the patch has been updated to include a small comment describing the behavior of this return value. Changelog: ws2_32: Use STATUS_MORE_PROCESSING_REQUIRED to indicate that the AcceptEx async should not send a completion.
