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 && !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.
