从套接字nonblockin winsock2接收数据？

Question

I am fairly new to cpp. I am wanting to be able to receive data via sock_stream. I want to pass the received data from SocketInfo->DataBuf.buf to an char recvArray[1024] buffer initiallized at the start of the program. I need to be able to check/parse and assemble numerical values out of my recvArray[]. How do I make this copy work? A couple of things I have tried get a compiler error "invalid conversion from char* to char"

//check sockets for for read or write notification
for(int i=0; Total>0 && i<TotalSockets; i++){
    LPSOCKET_INFORMATION SocketInfo = SocketList[i];

    //check if data incomming on each socket
    if( FD_ISSET(SocketInfo->Socket, &Reader)){
        Total--;
        SocketInfo->DataBuf.buf = SocketInfo->Buffer;
        SocketInfo->DataBuf.len = BUFFERSIZE;
        Flags = 0;
        //receive data
        SocketInfo->RecvBytes = sizeof(SocketInfo->DataBuf);
        check = WSARecv(SocketInfo->Socket, &(SocketInfo->DataBuf), 1, &(SocketInfo->RecvBytes), &Flags, NULL, NULL);
        //error checking
        if( check == SOCKET_ERROR){
            if( WSAGetLastError() != WSAEWOULDBLOCK){
                printf("base station client receive failed with error %d \n", WSAGetLastError());
                FreeSocketInformation(i); //shuts down client socket if no data
            }
            continue;
        }
        else{
            //receive bytes into array

            //print received bytes on screen
            printf("%s \n", SocketInfo->DataBuf.buf);
            //otherwise deal with data
            //need to copy to recvArray

            //if no bytes received then connection is closed.
            if( SocketInfo->RecvBytes == 0){
                FreeSocketInformation(i); //shuts down client socket if no data
                continue;
            }
        }
    } //end of read data from socket
}

//recieve data
SocketInfo->RecvBytes = sizeof(SocketInfo->DataBuf);
check = WSARecv(SocketInfo->Socket, &(SocketInfo->DataBuf), 1, &(SocketInfo->RecvBytes), &Flags, NULL, NULL);

Try to declare a new variable of type WSABUF lets us say,

WSABUF tempDataBuf;
check = WSARecv(SocketInfo->Socket, &(tempDataBuf), 1, &(SocketInfo->RecvBytes), &Flags, NULL, NULL);
 SocketInfo->DataBuf = tempDataBuf;
