Re: [libvirt] [libvirt-glib] [PATCH 1/2] libvirt-gobject-domain: Add _fetch_snapshots

This function can be used to fetch the snapshots of a domain (according to the given GVirDomainSnapshotListFlags) and save them in a domain-internal GHashTable. A function to access them from outside will be added in a later patch. --- libvirt-gobject/libvirt-gobject-domain.c | 59 ++++++++++++++++++++++++++++++++ libvirt-gobject/libvirt-gobject-domain.h | 36 +++++++++++++++++++ libvirt-gobject/libvirt-gobject.sym | 2 ++ 3 files changed, 97 insertions(+) diff --git a/libvirt-gobject/libvirt-gobject-domain.c b/libvirt-gobject/libvirt-gobject-domain.c index c6e30e5..f6b5837 100644 --- a/libvirt-gobject/libvirt-gobject-domain.c +++ b/libvirt-gobject/libvirt-gobject-domain.c @@ -38,6 +38,7 @@ struct _GVirDomainPrivate { virDomainPtr handle; gchar uuid[VIR_UUID_STRING_BUFLEN]; + GHashTable *snapshots; }; G_DEFINE_TYPE(GVirDomain, gvir_domain, G_TYPE_OBJECT); @@ -121,6 +122,8 @@ static void gvir_domain_finalize(GObject *object) g_debug("Finalize GVirDomain=%p", domain); + g_hash_table_unref (priv->snapshots); +
