// LANSHOW.C    A LANtastic NET SHOW clone
//
// (c) Copyright 1990, 1991 Adrian King.

//Initial revision.
//
//    This program is a single module example showing how to use both
//    the LANtastic API and the C library presented in "Running LANtastic".
//
//    The program is a 'clone' of the NET SHOW function of the LANtastic
//    NET utility. No attention has been paid to efficiency details.
//
//    Although error messages are displayed, very little error processing
//    is done.
//
//    Build notes:
//
//        This module must be linked with the NOS library (NOSLIB.LIB).
//
//        Make sure that nos.h and noslib.h are on the INCLUDE path for the
//        compiler.
//
