Detailed Description

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 inconsistency, __func__);                          goto bad;                                                                }                                                                            if (payload && payload_s)                                                    {                                                                                n = libnet_pblock_append(l, p, payload, payload_s);                          if (n == (u_int32_t) - 1)                                                    {                                                                                goto bad;                                                                }                                                                        }                                                                            
 

#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.
