Okay, I understand.
When the AddHandle function, I receive a fd (FileDescription), its value is
3... always... Is that normal ? Is that file descriptor on a socket or on a
file ? (In windows, when can use the WSAPoll function but it works on ly on
sockets)

?Hi,
Something I need to understant about callbacks:
if I install 2 callback via DomainEventRegisterAny (lifecycle
for the first and graphics for the second for example), am I
right if I said that the AddHandleFunc should be called 2 times ?
No, there is no direct relationship between the number of
calls to DomainEventRegister* and AddHandleFunc. In the
current impl we only call AddHandleFunc once per virConnect
object, but again that isn't guarenteed - different libvirt
drivers will invoke AddHandleFunc / AddTimeoutFunc a different
number of times, as is most suitable for their precise needs.
