<p class="MsoNormal"><span lang="EN-GB">in the source code, wherefore I wonder whether multicasting is supported at all on Windows. Also, samples like mckey are not included in the build.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">If multicasting works, is there any Windows sample out there on how to do it? Which API can I use? To be honest, I have never used multicasting before. Does it work just with the well-known IPv4 multicast addresses on
IB, too? <o:p></o:p></span></p>
