GPtrArray *
nm_device_filter_connections (NMDevice *device,
                              const GPtrArray *connections);

Filters a given array of connections for a given NMDevice object and returns connections which may be activated with the device. For example if device is a Wi-Fi device that supports only WEP encryption, the returned array will contain any Wi-Fi connections in connections that allow connection to unencrypted or WEP-enabled SSIDs. The returned array will not contain Ethernet, Bluetooth, Wi-Fi WPA connections, or any other connection that is incompatible with the device. To get the full list of connections see nm_client_get_connections().

Parameters

device

an NMDevice to filter connections for

 

connections

an array of NMConnections to filter.

[element-type NMConnection]

Returns

an array of NMConnections that could be activated with the given device . The array should be freed with g_ptr_array_unref() when it is no longer required.

WARNING: the transfer annotation for this function may not work correctly with bindings. See https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/305. You can filter the list yourself with nm_device_connection_valid().

nm_device_connection_valid ()

gboolean
nm_device_connection_valid (NMDevice *device,
                            NMConnection *connection);

Validates a given connection for a given NMDevice object and returns whether the connection may be activated with the device. For example if device is a Wi-Fi device that supports only WEP encryption, the connection will only be valid if it is a Wi-Fi connection which describes a WEP or open network, and will not be valid if it describes a WPA network, or if it is an Ethernet, Bluetooth, WWAN, etc connection that is incompatible with the device.

Parameters

device

an NMDevice to validate connection against

 

connection

an NMConnection to validate against device

 

Returns

TRUE if the connection may be activated with this device, FALSE if is incompatible with the device's capabilities and characteristics.


nm_device_connection_compatible ()

gboolean
nm_device_connection_compatible (NMDevice *device,
                                 NMConnection *connection,
                                 GError **error);

Validates a given connection for a given NMDevice object and returns whether the connection may be activated with the device. For example if device is a Wi-Fi device that supports only WEP encryption, the connection will only be valid if it is a Wi-Fi connection which describes a WEP or open network, and will not be valid if it describes a WPA network, or if it is an Ethernet, Bluetooth, WWAN, etc connection that is incompatible with the device.

This function does the same as nm_device_connection_valid(), i.e. checking compatibility of the given device and connection. But, in addition, it sets GError when FALSE is returned.

Parameters

device

an NMDevice to validate connection against

 

connection

an NMConnection to validate against device

 

error

return location for a GError, or NULL

 

Returns

TRUE if the connection may be activated with this device, FALSE if is incompatible with the device's capabilities and characteristics.

Parameters

neighbor

the NMLldpNeighbor

 

Since: 1.2


nm_lldp_neighbor_unref ()

void
nm_lldp_neighbor_unref (NMLldpNeighbor *neighbor);

Decreases the reference count of the object. If the reference count reaches zero, the object will be destroyed.

Since 1.32, ref-counting of NMLldpNeighbor is thread-safe.

Parameters

the NMLldpNeighbor

 

Since: 1.2


nm_lldp_neighbor_get_attr_names ()

char **
nm_lldp_neighbor_get_attr_names (NMLldpNeighbor *neighbor);

nm_lldp_neighbor_new ()

NMLldpNeighbor *
nm_lldp_neighbor_new (void);

Creates a new NMLldpNeighbor object.

Note that NMLldpNeighbor has no public API for mutating an instance. Also, libnm will not internally mutate a once exposed object. They are guaranteed to be immutable.

Since 1.32, ref-counting of NMLldpNeighbor is thread-safe.

This function is not useful, as there is no public API to actually modify the (empty) instance.

Returns

the new NMLldpNeighbor object.
