Question

I’ve been trying to figure this out for a while now and I need help because I’m out of ideas. My WSAEventselect function returns error number 10038.

Code:

        // Error checking....
        if(netEvent.iErrorCode[FD_ACCEPT_BIT] != 0)
        {
            int temp1 = WSAGetLastError();
            emit ClientErrorSignal();
            return;
        }

        // Initializing socket
        if((newClient = accept(this->info->socket, NULL, NULL)) == INVALID_SOCKET)
        {
            int temp2 = WSAGetLastError();
            emit ClientErrorSignal();
            return;
        }

        // This is where the error occurs
        if(WSAEventSelect(newClient, &this->info->event, FD_READ|FD_CLOSE) == SOCKET_ERROR)
        {
            int temp3 = WSAGetLastError();
            emit ClientErrorSignal();
            return;
        }

this->info is a struct that is passed into the thread.

typedef struct {
    SOCKET socket;
    int size;
    bool isTcp;
    WSAEVENT event;
} SINFO, *PSINFO;

According to the Winsock error reference, this is a WSAENOTSOCK error, meaning you’re trying to do something with an invalid socket handle. Without more information about where the error is occurring in your code I don’t think I can offer much more advice than that, but I’d suggest checking to ensure that you’re creating the socket correctly (perhaps the call to accept on an uninitialized socket is the culprit?)
