#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:.PP

                                 { { { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, \

IPv6 error code

#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.
