Examples of org.jnetpcap.Pcap.loop()

org.jnetpcap.Pcap.loop()
Collect a group of packets. pcap_loop() is similar to pcap_dispatch() except it keeps reading packets until cnt packets are processed or an error occurs. It does not return when live read timeouts occur. Rather, specifying a non-zero read timeout to pcap_open_live() and then calling pcap_dispatch() allows the reception and processing of any packets that arrive when the timeout occurs. A negative cnt causes pcap_loop() to loop forever (or at least until an error occurs). -1 is returned on an error; 0 is returned if cnt is exhausted; -2 is returned if the loop terminated due to a call to pcap_breakloop() before any packets were processed. If your application uses pcap_breakloop(), make sure that you explicitly check for -1 and -2, rather than just checking for a return value < 0. @param < T> handler's user object type @param cnt number of packets to read @param handler called when packet arrives for each packet @param user opaque user object @return 0 on success, -1 on error and -2 if breakloop was used interruptthe captue @since 1.2
