ConnectEx / DisconnectEx (EDITED)
Author
Hi,
Im trying to use the AcceptEx / ConnectEx / DisconnectEx functions in WinSock2. I've tried loading them with WSAIoctl, and it works fine for AcceptEx, but ConnectEx / DisconnectEx gives me an error:
WSAEOPNOTSUPP 10045L
The attempted operation is not supported for the type of object referenced.
I guess for some reason it's not supported for the socket I try to load it for.
I'm using Windows XP Pro SP2.
code:
That one works, but if I try the same for DisconnectEx or ConnectEx I get error 10045.
Do I need to do something else with the socket before I can load all the functions?
I've read all the MSDN pages and googled for it but I find the same code and the same documentation everywhere, but it doesn't work for me, and I can't seem to find what I'm doing wrong or why it wouldn't work =)
I have tried binding the socket first also, as well as connecting it and a few other things..
MSDN says the functions are all available in Windows XP.
EDIT2: It seems I dont even have to load the AcceptEx function since it already has a prototype in MSWsock.h and I can link to it in mswsock.lib.

The actual arguments for socket() and ioctl() are probably quite relevant for this question.
LPFN_CONNECTEX fnConnectEx = NULL;
GUID gufn = WSAID_CONNECTEX;
DWORD dwBytes;
WSAIoctl(m_hSocket, SIO_GET_EXTENSION_FUNCTION_POINTER, &gufn, sizeof(gufn), &fnConnectEx, sizeof(fnConnectEx), &dwBytes, NULL, NULL);
I haven't tried it on XP recently, but it worked for me on Win2003
