NAME

       libnet - A C library for packet creation and injection

SYNOPSIS

       #include <libnet.h>

DESCRIPTION

       libnet is a packet assembly library that provides a portable interface for packet creation and injection.

       It is a high-level API that allows an application programmer to construct and inject network packets.
       libnet provides a simplified interface for low-level network packet shaping, handling and injection.

       libnet hides much of the tedium of packet creation from the application programmer such as multiplexing,
       buffer management, arcane packet header information, byte-ordering, OS-dependent issues, and much more.
       libnet features portable packet creation interfaces at the IP and link layer, as well as a host of
       supplementary and complementary functionality. Using libnet, quick and simple packet assembly
       applications can be whipped up with little effort.  With a bit more time, more complex programs can be
       written (traceroute(8) and ping(8) were easily rewritten using libnet and pcap(3).

       When building applications with libnet we recommend using pkg-config(1) to detect the precense and
       required version of libnet.  The libnet-config(1) script is still bundled in the libnet distribution, but
       is considered to be deprecated in favor of pkg-config(1).  Both can be used to get compiler and linker
       flags of the installed libnet library, as well as provide other useful information.  For applications
       using GNU autotools, we recommend using the PKG_PROG_PKG_CONFIG and PKG_CHECK_MODULES m4 macros.

       NOTE: If you are writing your application with libnet, include libnet.h, which will include any
       additional header for you, rather than including libnet/libnet-functions.h, libnet/libnet-macros.h or any
       of the others.

BACKWARDS COMPATIBILITY

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