I mean it's really hard to get applicable info from it because it just lists a list of functions without introducing any concepts first. I find the doc in share/gtk-doc directory. Do I miss anything? Is there any sample code or introduction to its concepts? BTW, Does libvirt supply any function which can return the process identifier of the domain? Thanks
