Libvirt set of C code examples

The examples are stored per section depending on the main focus of the example:

Informations :
- info1.c: Extract informations about Xen domain 0
Scheduling :
- suspend.c: Suspend a domain and then resume its execution

Getting the compilation options and libraries dependancies needed to generate binaries from the examples is best done on Linux/Unix by using the pkg-config data which should have been installed as part of make install step or when installing the libvirt development package:

gcc -o example example.c `pkg-config libvirt --libs`
