Hinweise
The WSAResetEvent function is used to set the state of the event object to nonsignaled.
The proper way to reset the state of an event object used with the WSAEventSelect function is to pass the handle of the event object to the WSAEnumNetworkEvents function in the hEventObject parameter. This will reset the event object and adjust the status of active FD events on the socket in an atomic fashion.
