Being binary compatible with BeOS R5 has made thislibrary implementation tedious. To counter this, the libnetapi.so sharedlibrary was developed. It contains thin C++ classes wrapping the Csockets POSIX/BSD API into these BNet* classes we're used under BeOS.The stack driver is the interface between libnet.so and the real stackbehind it, hosted by the network stack kernel modules. Its purposesinclude:-# Providing sockets to file descriptors translation support-# Providing support for select() on sockets-# Loading the network stack on first access, and then keeping it forfurther accessesThe following diagram illustrates the network stack design on Haiku:\image html obos_net_stack_design_1.gifThe Network Kit includes a handful of useful networking related appsincluding ping, ifconfig, route, traceroute, and arp.See the User Guide for more information about the<a href="http://haiku-os.org/docs/userguide/en/preferences/network.html">Network preferences app</a>included as part of the Network Kit.*/
