Information on these protocols can be found inthe following books:<ul><li></li><i>Internetworking with TCP/IP Volume III, </i>by Douglas Comer and David Stevens<li></li><i>UNIX Network Programming, </i>by Richard Stevens<li></li><i>The Design and Implementation of the 4.3 BSD UNIX Operating System, </i>by Leffler, McKusick, Karels and Quarterman<p></ul><p>The <b><a href="./netShow.html#netShowInit">netShowInit</a>( )</b> routine links the network show facility into the VxWorkssystem.
