So if I understand well, are you saying that if I use gnulib windows version via C# (pinvoke, this kind of magic) I will have access to poll function ? Intersting, I'll take a look. I hope gnulib if published via a dll under windows, if so, I'm pretty sure I can use it with C# regards Arnaud ---------------------------------------- De: "Eric Blake" <eblake(a)redhat.com&gt; Envoyé: lundi 31 janvier 2011 19:37 A: arnaud.champion(a)devatom.fr Objet: Re: [libvirt] Raising events for testing On 01/30/2011 05:21 AM, arnaud.champion(a)devatom.fr wrote: Libvirt uses gnulib to guarantee that poll() works on file descriptors; all socket operations are magically mapped by gnulib to behave like file descriptors, so that you don't have to worry about the (less-useful) restrictions of windows poll() only working on sockets. There is - it involves using gnulib. But that is only for C and C++ - I have no idea how this translates over to C#. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
