I'm writing a program which reads live captures and processes them. I'm using pcap_next_ex for capturing and it returns -1 and -2 unexpectdly. Will it be nice to use pcap_loop rather than pcap_next_ex? Which one is more efficient? Is the problem associated with read time out?

Well, this is really a [email protected] question, but:

  1. On what operating system is this?

  2. Are you calling pcap_breakloop() in your program?

  3. When pcap_next_ex() returns -1, what does pcap_geterr() return?
