Symptoms

Consider the following scenario:

In Windows Embedded Compact 7, you open a socket from a kernel driver and use an asynchronous IO on the socket.
You run the WSAEventSelect function together with the FD_CLOSE flag, and then you close the socket by using the closesocket function.
You call a WaitForSingleObject function that uses same event handles that are used for the WSAEventSelect function.

In this scenario, the WaitForSingleObject function returns WAIT_FAILED. After the call to the closesocket function, the WSAEnumNetworkEvents and WSAWaitForMultipleEvents functions fail with a WSA_INVALID_HANDLE error.

Note The nonblocking closesocket function initiates graceful socket closure. This process may involve some data exchange. The calling driver must be able to use the WSAWaitForMultipleEvents and WSAEnumNetworkEvents functions in order to wait for graceful socket closure.
