NAME

6       libnet - A C library for packet creation and injection
7

SYNOPSIS

9       #include <libnet.h>
10

DESCRIPTION

12       libnet is a packet assembly library that provides a portable interface
13       for packet creation and injection.
14
15       It is a high-level API that allows an application programmer to
16       construct and inject network packets. libnet provides a simplified
17       interface for low-level network packet shaping, handling and injection.
18
19       libnet hides much of the tedium of packet creation from the application
20       programmer such as multiplexing, buffer management, arcane packet
21       header information, byte-ordering, OS-dependent issues, and much more.
22       libnet features portable packet creation interfaces at the IP and link
23       layer, as well as a host of supplementary and complementary
24       functionality. Using libnet, quick and simple packet assembly
25       applications can be whipped up with little effort.  With a bit more
26       time, more complex programs can be written (traceroute(8) and ping(8)
27       were easily rewritten using libnet and pcap(3).
28
29       When building applications with libnet we recommend using pkg-config(1)
30       to detect the precense and required version of libnet.  The
31       libnet-config(1) script is still bundled in the libnet distribution,
32       but is considered to be deprecated in favor of pkg-config(1).  Both can
33       be used to get compiler and linker flags of the installed libnet
34       library, as well as provide other useful information.  For applications
35       using GNU autotools, we recommend using the PKG_PROG_PKG_CONFIG and
36       PKG_CHECK_MODULES m4 macros.
37
38       NOTE: If you are writing your application with libnet, include
39       libnet.h, which will include any additional header for you, rather than
40       including libnet/libnet-functions.h, libnet/libnet-macros.h or any of
41       the others.

BACKWARDS COMPATIBILITY

44       Your old code (circa libnet 1.0.x) WILL NOT WORK with libnet> >=1.1.x.
45       See doc/MIGRATION.md for easy steps on porting your old code.
