Hi all, I am using libipq for userspace programming on netfilter. I am having problems to determine whether there are any packets in the ip_queue before I call the function ipq_read(). I just don't wish to call ipq_read() when there is no packet in the ip_queue, because I need my program to do other things rather than waiting for a packet arriving (after calling ipq_read(), the program will stop and wait for some time or until a packet coming from the kernel). Are there anybody on the list who has any idea about this? BTW, may I ask whether this is the proper list to ask about netfilter/libipq programming, since it seems few people on the list talking about this kind of questions?
