[transfer none]


nm_access_point_get_bssid ()

const char *
nm_access_point_get_bssid (NMAccessPoint *ap);

Gets the Basic Service Set ID (BSSID) of the Wi-Fi access point.

Parameters

ap

a NMAccessPoint

 

Returns

the BSSID of the access point. This is an internal string and must not be modified or freed.


nm_access_point_get_frequency ()

guint32
nm_access_point_get_frequency (NMAccessPoint *ap);

Gets the frequency of the access point in MHz.

Parameters

ap

a NMAccessPoint

nm_access_point_get_mode ()

NM80211Mode
nm_access_point_get_mode (NMAccessPoint *ap);

Gets the mode of the access point.

Parameters

ap

a NMAccessPoint

 

Returns

the mode


nm_access_point_get_max_bitrate ()

guint32
nm_access_point_get_max_bitrate (NMAccessPoint *ap);

Gets the maximum bit rate of the access point in kbit/s.

Parameters

ap

a NMAccessPoint

Gets the current signal strength of the access point as a percentage.

Parameters

ap

a NMAccessPoint

nm_access_point_get_last_seen ()

int
nm_access_point_get_last_seen (NMAccessPoint *ap);

Returns the timestamp (in CLOCK_BOOTTIME seconds) for the last time the access point was found in scan results. A value of -1 means the access point has not been found in a scan.

Parameters

ap

a NMAccessPoint

 

Returns

the last seen time in seconds

Since: 1.2


nm_access_point_filter_connections ()

GPtrArray *
nm_access_point_filter_connections (NMAccessPoint *ap,
                                    const GPtrArray *connections);

Filters a given array of connections for a given NMAccessPoint object and returns connections which may be activated with the access point. Any returned connections will match the ap 's SSID and (if given) BSSID and other attributes like security settings, channel, etc.

To obtain the list of connections that are compatible with this access point, use nm_client_get_connections() and then filter the returned list for a given NMDevice using nm_device_filter_connections() and finally filter that list with this function.

Parameters

ap

an NMAccessPoint 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 ap . The array should be freed with g_ptr_array_unref() when it is no longer required.

[transfer container][element-type NMConnection]


nm_access_point_connection_valid ()

gboolean
nm_access_point_connection_valid (NMAccessPoint *ap,
                                  NMConnection *connection);

Validates a given connection against a given Wi-Fi access point to ensure that the connection may be activated with that AP. The connection must match the ap 's SSID, (if given) BSSID, and other attributes like security settings, channel, band, etc.

Parameters

ap

an NMAccessPoint to validate connection against

 

connection

an NMConnection to validate against ap

 

Returns

TRUE if the connection may be activated with this Wi-Fi AP, FALSE if it cannot be.
