[libvirt-users] virConnectClose

[llilulu]

libvirt
version: 3.4.0

    When invoke virConnectDomainEventRegisteAny register event on a hypervisor connection, before virConnecClose, should I invoke virConnectDomainEventDeregisterAny. If a hypervisor connection close unexpected, call virConnectDomainEventDeregisterAny will return error? Can tell me more detail about event? This libvirt doc not more description.
    Thanks
