[20:10] <Damn3d> I'm using a select() loop to check for readability of sockets and listeners. Is this possible to use select() to handle non-blocking connect() ?

[20:16] <Damn3d> Ensiferum Do I have to use additional set for them? Cause currently I'm storing both listeners + sockets at the same set
[20:17] <Ensiferum> Damn3d: you make the socket non-blocking, then you call connect and check the socket for readability
[20:17] <Ensiferum> when its signaled to be read the connect has finished
[20:17] <Ensiferum> and then you check the socket for error code
[20:18] <Damn3d> Hm..
[20:18] <Damn3d> So I'll be notified by select() by the same way as I am when sockets are readable?
[20:19] <Ensiferum> yeah
[20:20] <Damn3d> How do you check for socket error code?
[20:20] * Krabbe is now known as krabbe
[20:21] <Ensiferum> you call getsockopt
[20:22] * pnk|[DC]remagT (~borim@root.on.every.dial-in.org) has joined #c++
[20:23] <Ensiferum> you have to note that when you call connect on a non-blocking socket you'll get an error code
[20:23] <Ensiferum> and then you'll have to check the specific error with errno/WSAGetError
[20:23] <Ensiferum> and you get EINPROGRESS/WSAEWOULDBLOCK

[20:27] * pnk|[DC]remagT (~borim@root.on.every.dial-in.org) has left #c++
[20:27] <Damn3d> Okay, So I'd need to create a variable in order to check if the socket is already connected, right ? (Calling getsockopt() on every read availability would be stupid)
[20:27] <Ensiferum> just call getsockopt when the connecting socket is signaled
[20:28] <Ensiferum> its only signaled when the connect is ready
[20:28] <Ensiferum> FD_SET read;
[20:28] <Ensiferum> FD_ZERO(&read);
[20:29] <Ensiferum> FD_SET(connection_fd, &read); select(..., &read, NULL, NULL, NULL); if (FD_ISSET(connection_fd, &read)) getsockopt(...)
[20:29] <Ensiferum> btw are you on *nix or win?
[20:29] <Damn3d> Linux
[20:30] <Ensiferum> aight
[20:30] <Damn3d> You said that I'd be notified by the same way as on readability. So how can I check if I'm aiting for connect() or for recv() ?
[20:30] <Damn3d> WAITING*
[20:30] <Damn3d> without caps*.. :P
[20:30] <Ensiferum> well that you need to take care of yourself
[20:31] <Damn3d> Ok
