Hi Having a look at asio as a possible solution for a cleanup of an existing app. It would be nice to extend asio to include non-socket file descriptors. I realise that this would not be portable to Windows, but does asio provide extension points to add this functionality, also adding PF_LOCAL sockets would be handy as well although these could be switched to a PF_INET implementation with an acceptable performance penalty. Has anyone experimented with extensions like these? TIA -- Bill Somerville This message has been scanned by MailController - www.MailController.altohiway.com
