    Question Error on Async socket startup!

    I will post my code. When I use WSAGetLastError(); it connect() fails, I have a MessageBox(...) with the error and it comes up and Async sockets won't start. I will attach my code!

    2 things.....

    [list=1][*]itoa()'s third param is not the amount of chars in the buffer...it is the base....therefore for decimal use 10 instead of 100[*]The error returned is 10035. This I believe is because you are selecting a nonblocking socket and then trying to call select on it.....[/list=1]

    To tell you the truth I havent done this stuff in ages......but I guess the program should just listen after selecting up the socket.....

    Have a search on google for more help, or wait for someone who remembers more about it than me...

    This is almost like saying freezer burn or jumbo shrimp...it just doesn't work . Blocking and asynchronous sockets are two very different things; blocking sockets will not return during a function call until something happens, while asynchronous sockets are more like the Windows message system we've all grown to love and post notifications.

    You might want to visit http://www.hal-pc.org/~johnnie2/winsock.html and gamedev's async article. Beware of the latter tutorial...FD_READ is not nearly as easy as what it seems.

    Regarding your questions in the previous post, you do not necessarily have to handle FD_CONNECT and FD_ACCEPT messages at all. In fact, FD_CONNECT is used almost exclusively in clients while servers interpret FD_ACCEPT. Like any other standard Winproc message, you can handle only what you want and disregard the rest.

    I agree with Fordy on error 10035.
