## 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
