However, from time to time, I suspect there are some packet loss, which are corrected by the kernel (hell, TCP is reliable, isn't it :-), but I'd like to know if an application can detect this (well, I don't want to be notified of a packet loss once detected, but I'd like to get some stats before closing the connection). Is there something possible ? Some ioctl ? Some /proc/magic-interface ?
