BUG: Winsock 2 Issue when Not Using the FD_CONNECT Notification

ID: Q199434


The information in this article applies to:


SYMPTOMS

If a Winsock 2 application connects to a peer application and then only sets FD_WRITE in the lNetworkEvents bitmask when calling WSAEventSelect(), but does not also set FD_CONNECT, then the application will hang in WSAWaitForMultipleEvents() after the socket gets connected.


RESOLUTION

A simple workaround solution to this is to simply set FD_CONNECT in the lNetworkEvents bitmask when calling WSAEventSelect, even if a connection has already been established using connect or WSAConnect.


STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
