I'm sorry, I should've made my question clearer, I'm using TCP sockets. I'm just trying to test whether a connection has been made by connecting again and catching the error. I know there are better ways of doing this, but I was surprised when the second connect() succeeded. I've tested this out on other OS's SunOS, FreeBSD, IRIX and Win2k( here i used python to call the underlying windows implementation), and a second connect() always returns an error.
