Appendix A: IPv4-only Source Code
This appendix provides the source code for the Platform Software Development Kit (SDK) samples Simplec.c and Simples.c, which are used throughout this IPv6 guide as examples:
Warning This appendix illustrates code that is IPv4-specific; do NOT use this code in your applications.
This code is included in this guide to contrast the IP-version agnostic code provided in Appendix B. This sample code is provided for comparison purposes, and to provide a clear and readily available reference while reading this IPv6 guide. An IP version agnostic version of this source code is provided in Appendix B: IP-version Agnostic Source Code.
Note By comparing the source code in Appendix A (IPv4 only) and Appendix B (IP version agnostic), you get a sense of the changes necessary to modify your Windows Sockets application to add support for IPv6.
