Re: [libvirt] [PATCH v2] gobject: Add wrapper virDomainSetTime()

--- This version: * Replaces the seconds and nseconds arguments by a GDateTime. * Drops the use of flags argument, since caller can specify the only flag currently possible (VIR_DOMAIN_TIME_SYNC) by simply passing a NULL as the GDateTime argument. * Add some needed articles to doc comment. libvirt-gobject/libvirt-gobject-domain.c | 121 +++++++++++++++++++++++++++++++ libvirt-gobject/libvirt-gobject-domain.h | 15 +++- libvirt-gobject/libvirt-gobject.sym | 9 +++ 3 files changed, 144 insertions(+), 1 deletion(-) diff --git a/libvirt-gobject/libvirt-gobject-domain.c b/libvirt-gobject/libvirt-gobject-domain.c index 34eb7ca..debae2d 100644 --- a/libvirt-gobject/libvirt-gobject-domain.c +++ b/libvirt-gobject/libvirt-gobject-domain.c @@ -1886,3 +1886,124 @@ gboolean gvir_domain_get_has_current_snapshot(GVirDomain *dom, return TRUE; } + +/** + * gvir_domain_set_time: + * @dom: the domain + * @date_time: (allow-none)(transfer none): the time to set as #GDateTime. + * @flags: Unused, Pass 0.
