At this point if fConnected is FALSE, we have to check GetLastError() for: ERROR_PIPE_CONNECTED: client has already connected before we have called ConnectNamedPipe. this is quite common depending on the timings and indicates success ERROR_IO_PENDING: Since we're using ConnectNamedPipe asynchronously here, the function returns immediately and this error code simply indicates that the operation is still in progress. Hence we have to wait for the completion event and use GetOverlappedResult to query the actual result of the operation (note that the lpNumberOfBytesTransferred parameter is undefined/useless for a ConnectNamedPipe operation)
