Description

Functions

nm_device_tun_get_hw_address ()

const char *
nm_device_tun_get_hw_address (NMDeviceTun *device);

Gets the hardware (MAC) address of the NMDeviceTun

Parameters

device

a NMDeviceTun

  

Returns

the hardware address. This is the internal string used by the device, and must not be modified.

Since: 1.2

nm_device_tun_get_mode ()

const char *
nm_device_tun_get_mode (NMDeviceTun *device);

Returns the TUN/TAP mode for the device.

Parameters

device

a NMDeviceTun

  

Returns

'tun' or 'tap'

Since: 1.2

nm_device_tun_get_owner ()

gint64
nm_device_tun_get_owner (NMDeviceTun *device);

Gets the tunnel owner.

Parameters

device

a NMDeviceTun

  

Returns

the uid of the tunnel owner, or -1 if it has no owner.

Since: 1.2

nm_device_tun_get_group ()

gint64
nm_device_tun_get_group (NMDeviceTun *device);

Gets the tunnel group.

Parameters

device

a NMDeviceTun

  

Returns

the gid of the tunnel group, or -1 if it has no owner.

Since: 1.2

nm_device_tun_get_no_pi ()

gboolean
nm_device_tun_get_no_pi (NMDeviceTun *device);

nm_device_tun_get_vnet_hdr ()

gboolean
nm_device_tun_get_vnet_hdr (NMDeviceTun *device);

Returns whether the NMDeviceTun has the IFF_VNET_HDR flag.

Parameters

device

a NMDeviceTun

  

Returns

TRUE if the device has the flag, FALSE otherwise

Since: 1.2

nm_device_tun_get_multi_queue ()

gboolean
nm_device_tun_get_multi_queue (NMDeviceTun *device);

Returns whether the NMDeviceTun has the IFF_MULTI_QUEUE flag.

Parameters

device

a NMDeviceTun

  

Returns

TRUE if the device doesn't have the flag, FALSE otherwise

Since: 1.2
