Well that's one aspect. Additionally ICS uses the message-based Windows non-blocking socket API. There doesn't exist something similiar on other platforms, at least not at such a low level AFAIK. Means non-blocking behavior had to be implemented using threads (as Windows implements that as well, under the hood) using the platform messaging/notification stuff available. The ICS for Kylix Angus mentioned isn't true xplat, though it made porting Windows ICS apps to Linux easier. That version will certainly run on MAC OSX/POSIX as well with just a few changes. However if we want a true cross platform ICS major parts would have to be rewritten from scratch which were a lot of work and porting existing code to such a ICSX certainly won't be a very simple task. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
