Reading Packets From The Queue

• In order to read a message, we use the 'ipq_read()' function:

  unsigned char buf[BUFSIZE];
  int rc = ipq_read(h, buf, BUFSIZE, 0 /*blocking*/);
  

• In order to check what type of message we got (packet, error....):

  int msg_type = ipq_message_type(buf);

• The interesting message type is IPQM_PACKET - a real (IP) packet.
