#49 Non blocking socket connect() errno setting

[Richard Quirk]

connect() on a non blocking socket should give some way to know that the connection is not ready. This is done on POSIX by returning an error and setting errno to EINPROGRESS. I've used the attached patch for a while, and it means you can do:

int result = connect(tcp_socket, (struct sockaddr*)&socketAddress, addrlen);

if (result != 0 && errno == EINPROGRESS) {
// set some flags and run select or whatever
} else if (result == 0) {
// connected ok
} else {
// fail or whatever
}

It'd be great if this could go into your dswifi so I didn't have to remember to patch it each time! :-)
