Define Documentation

   #define for_each_context_in_cq(l)   for (l = libnet_cq_head();
       libnet_cq_last(); l = libnet_cq_next())
       Provides an interface to iterate through the context queue of libnet
       contexts. Before calling this macro, be sure to set the queue using
       libnet_cq_head().

   #define IN6ADDR_ERROR_INIT
       Value:

       { { { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,                                  0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,                                  0xff, 0xff } } }
       IPv6 error code

   #define LIBNET_DO_PAYLOAD(l, p)
       Value:

       if ((payload && !payload_s) || (!payload && payload_s))                      {                                                                                snprintf(l->err_buf, LIBNET_ERRBUF_SIZE,                                             ’%s(): payload inconsistency0, __func__);                          goto bad;                                                                }                                                                            if (payload && payload_s)                                                    {                                                                                n = libnet_pblock_append(l, p, payload, payload_s);                          if (n == (u_int32_t) - 1)                                                    {                                                                                goto bad;                                                                }                                                                        }                                                                            .fi

   #define LIBNET_DONT_RESOLVE   0
       Used for libnet’s name resolution functions, specifies that no DNS
       lookups should be performed and the IP address should be kept in
       numeric form.

   #define LIBNET_ERRBUF_SIZE   0x100
       The libnet error buffer is 256 bytes long.

   #define LIBNET_MAX_PACKET   0xffff
       The biggest an IP packet can be -- 65,535 bytes.

   #define LIBNET_MAXOPTION_SIZE   0x28
       IP and TCP options can be up to 40 bytes long.

   #define LIBNET_OFF   1
       Used several places, to specify ’on’ or ’one’

   #define LIBNET_ON   0
       Used several places, to specify ’on’ or ’one’

   #define LIBNET_PR2   0
       Used for libnet_get_prand() to specify function disposition

   #define LIBNET_RESOLVE   1
       Used for libnet’s name resolution functions, specifies that a DNS
       lookup can be performed if needed to resolve the IP address to a
       canonical form.
