Detailed Description

libnet macros and symbolic constants

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_s && !payload)                                                   {                                                                                snprintf(l->err_buf, LIBNET_ERRBUF_SIZE,                                             '%s(): payload inconsistency0, __func__);                          goto bad;                                                                }                                                                            if (payload_s)                                                               {                                                                                n = libnet_pblock_append(l, p, payload, payload_s);                          if (n == (uint32_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.
