Description

The TrackerNetworkProvider allows different backends to be written for retrieving network connectivity status information. This can be used to avoid heavy transfers when on a slow connection, or on a connection where costs may apply. Currently, there are two implementations. The NetworkManager one uses NetworkManager, and the Dummy one will always expose the network as connected, no matter what the connectivity status actually is.

enum TrackerNetworkProviderStatus

typedef enum {
	TRACKER_NETWORK_PROVIDER_DISCONNECTED,
	TRACKER_NETWORK_PROVIDER_UNKNOWN,
	TRACKER_NETWORK_PROVIDER_GPRS,
	TRACKER_NETWORK_PROVIDER_EDGE,
	TRACKER_NETWORK_PROVIDER_3G,
	TRACKER_NETWORK_PROVIDER_LAN
} TrackerNetworkProviderStatus;

Enumerates the different types of connections that the device might use when connected to internet. Note that not all providers might provide this information.

TRACKER_NETWORK_PROVIDER_DISCONNECTED: Network is disconnected TRACKER_NETWORK_PROVIDER_UNKNOWN: Network status is unknown TRACKER_NETWORK_PROVIDER_GPRS: Network is connected over a GPRS connection TRACKER_NETWORK_PROVIDER_EDGE: Network is connected over an EDGE connection TRACKER_NETWORK_PROVIDER_3G: Network is connected over a 3G or faster (HSDPA, UMTS, ...) connection TRACKER_NETWORK_PROVIDER_LAN: Network is connected over a local network connection. This can be ethernet, wifi, etc.

tracker_network_provider_get ()

TrackerNetworkProvider * tracker_network_provider_get   (void);

This function MUST be defined by the implementation of TrackerNetworkProvider.

For example, tracker-network-provider-network-manager.c should include this function for a NetworkManager implementation.

Only one implementation can exist at once.

Returns :

a TrackerNetworkProvider.

Since 0.9


tracker_network_provider_get_name ()

gchar *             tracker_network_provider_get_name   (TrackerNetworkProvider *provider);

At the moment there are only two providers, "Dummy" and "NetworkManager". Either of these is what will be returned unless new providers are written.

provider :

a TrackerNetworkProvider

Returns :

a newly allocated string representing the "name" which must be freed with g_free().

tracker_network_provider_get_status ()

TrackerNetworkProviderStatus  tracker_network_provider_get_status
                                                        (TrackerNetworkProvider *provider);

This function calls the network provider's "get_status" implementation.

provider :

a TrackerNetworkProvider

Returns :

a TrackerNetworkProviderStatus decribing the current network status.
