Some information is actually available into the tcp_info structure (defined in /usr/include/linux/tcp.h) and filled in with a call to getsockopt(IPPROTO_TCP, TCP_INFO), for instance the tcpi_unacked member sounds like a good candidate -- I didn't check the kernel side implementation, which I think it's the only true reference available for this stuff. -- Giuseppe D'Angelo _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
