Description
GeoclueProvider contains the methods and signals common to all Geoclue providers. It is part of the public C client API which uses D-Bus to communicate with the actual provider.
A GeoclueProvider is not explicitly created. Instead any provider object can be cast to GeoclueProvider. Using a GeocluePosition as example here:
1 2 3 4 5 6 7 8 9 10 11 |
GeocluePosition *pos; char *name; GError *error; pos = geoclue_position_new ("org.freedesktop.Geoclue.Providers.Example", "/org/freedesktop/Geoclue/Providers/Example"); if (geoclue_provider_get_provider_info (GEOCLUE_PROVIDER (pos), &name, NULL, &error)) { g_print ("name = %s", name); } |
GeoclueProvider can be used to obtain generic information about the provider and to set provider options.

geoclue_provider_get_provider_info_async ()
void geoclue_provider_get_provider_info_async (GeoclueProvider *provider,GeoclueProviderInfoCallback callback,gpointer userdata);
Asynchronous version of geoclue_provider_get_provider_info(). Function returns
(essentially) immediately and calls callback when info is available or
when there is an error.

A GeoclueProviderInfoCallback function that will be called when info is available |
|
pointer for user specified data |
geoclue_provider_get_status ()
gboolean geoclue_provider_get_status (GeoclueProvider *provider,GeoclueStatus *status,GError **error);
Obtains the current status of the provider.
|
A GeoclueProvider object |
|
Pointer for returned status as GeoclueStatus |
|
Pointer for returned GError or NULL
|
Returns : |
TRUE on success |
geoclue_provider_get_status_async ()
void geoclue_provider_get_status_async (GeoclueProvider *provider,GeoclueProviderStatusCallback callback,gpointer userdata);
Asynchronous version of geoclue_provider_get_status(). Function returns
(essentially) immediately and calls callback when status is available or
when there is an error.
|
A GeoclueProvider object |
|
A GeoclueProviderStatusCallback function that will be called when return values are available |
|
pointer for user specified data |
geoclue_provider_set_options ()
gboolean geoclue_provider_set_options (GeoclueProvider *provider,GHashTable *options,GError **error);
Sets the options on the provider.
|
A GeoclueProvider object |
|
A GHashTable containing the options |
|
Pointer for returned GError or NULL
|
Returns : |
TRUE if setting options succeeded |
geoclue_provider_set_options_async ()
void geoclue_provider_set_options_async (GeoclueProvider *provider,GHashTable *options,GeoclueProviderOptionsCallback callback,gpointer userdata);
Asynchronous version of geoclue_provider_set_options(). Function returns
(essentially) immediately and calls callback when options have been set or
when there is an error.
|
A GeoclueProvider object |
|
A GHashTable of options |
|
A GeoclueProviderOptionsCallback function that will be called when options are set |
|
pointer for user specified data |

Signal Details
The "status-changed" signal
void user_function (GeoclueProvider *provider,
gint status,
gpointer user_data) : No Recursion
The status-changed signal is emitted each time the provider status changes
