Macro Definition 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_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.
