/*=========================================================================*\
* UDP socket object implementation (inherits from sock and inet)
* UDP class: inherits from Socked and Internet domain classes and provides
* all the functionality for UDP objects.
* Lua methods:
* send: using compat module
* sendto: using compat module
* receive: using compat module
* receivefrom: using compat module
* setpeername: using internet module
* setsockname: using internet module
* Global Lua functions:
* udp: creates the udp object
*
* RCS ID: $Id$
