Attributes
Public Instance Methods
Call
virNodeDeviceDestroy[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceDestroy]
to shutdown the node device.
static VALUE libvirt_nodedevice_destroy(VALUE s) { gen_call_void(virNodeDeviceDestroy, conn(s), nodedevice_get(s)); }
Call
virNodeDeviceDettach[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceDettach]
to detach the node device from the node.
static VALUE libvirt_nodedevice_detach(VALUE s) { gen_call_void(virNodeDeviceDettach, conn(s), nodedevice_get(s)); }
Call
virNodeDeviceFree[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceFree]
to free the node device object. After this call the node device object is
no longer valid.
static VALUE libvirt_nodedevice_free(VALUE s) { gen_call_free(NodeDevice, s); }
Call
virNodeDeviceListCaps[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceListCaps]
to retrieve a list of capabilities of the node device.
static VALUE libvirt_nodedevice_list_caps(VALUE c) { int r, num; virConnectPtr conn = connect_get(c); virNodeDevicePtr nodedev = nodedevice_get(c); char **names; num = virNodeDeviceNumOfCaps(nodedev); _E(num < 0, create_error(e_RetrieveError, "virNodeDeviceNumOfCaps", conn)); if (num == 0) /* if num is 0, don't call virNodeDeviceListCaps function */ return rb_ary_new2(num); names = ALLOC_N(char *, num); r = virNodeDeviceListCaps(nodedev, names, num); if (r < 0) { xfree(names); rb_exc_raise(create_error(e_RetrieveError, "virNodeDeviceListCaps", conn)); } return gen_list(num, &names); }
Call
virNodeDeviceGetName[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceGetName]
to retrieve the name of the node device.
static VALUE libvirt_nodedevice_name(VALUE c) { gen_call_string(virNodeDeviceGetName, conn(c), 0, nodedevice_get(c)); }
Call
virNodeDeviceNumOfCaps[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceNumOfCaps]
to retrieve the number of capabilities of the node device.
static VALUE libvirt_nodedevice_num_of_caps(VALUE c) { gen_call_int(virNodeDeviceNumOfCaps, conn(c), nodedevice_get(c)); }
Call
virNodeDeviceGetParent[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceGetParent]
to retrieve the parent of the node device.
static VALUE libvirt_nodedevice_parent(VALUE c) { /* unfortunately we can't use gen_call_string() here because * virNodeDeviceGetParent() returns NULL as a valid value (when this * device has no parent. Hand-code it instead */ const char *str; str = virNodeDeviceGetParent(nodedevice_get(c)); if (str == NULL) return Qnil; else return rb_str_new2(str); }
Call
virNodeDeviceReAttach[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceReAttach]
to reattach the node device to the node.
static VALUE libvirt_nodedevice_reattach(VALUE s) { gen_call_void(virNodeDeviceReAttach, conn(s), nodedevice_get(s)); }
Call
virNodeDeviceReset[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceReset]
to reset the node device.
static VALUE libvirt_nodedevice_reset(VALUE s) { gen_call_void(virNodeDeviceReset, conn(s), nodedevice_get(s)); }
Call
virNodeDeviceGetXMLDesc[http://www.libvirt.org/html/libvirt-libvirt.html#virNodeDeviceGetXMLDesc]
to retrieve the XML for the node device.
static VALUE libvirt_nodedevice_xml_desc(int argc, VALUE *argv, VALUE s) { VALUE flags; rb_scan_args(argc, argv, "01", &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_string(virNodeDeviceGetXMLDesc, conn(s), 1, nodedevice_get(s), NUM2UINT(flags)); }
