enum LocationGPSDControlInterval

typedef enum {
	LOCATION_INTERVAL_DEFAULT = 0x0000,
	LOCATION_INTERVAL_1S = 0x000A,
	LOCATION_INTERVAL_2S = 0x0014,
	LOCATION_INTERVAL_5S = 0x0032,

	LOCATION_INTERVAL_60S = 0x0258,
	LOCATION_INTERVAL_120S = 0x04B0,
} LocationGPSDControlInterval;

Enum representing valid values for the intervals between fixes. Note that only these constants can be specified for the preferred interval value.

enum LocationGPSDControlError

typedef enum {
	LOCATION_ERROR_USER_REJECTED_DIALOG,
	LOCATION_ERROR_USER_REJECTED_SETTINGS,
	LOCATION_ERROR_BT_GPS_NOT_AVAILABLE,
	LOCATION_ERROR_METHOD_NOT_ALLOWED_IN_OFFLINE_MODE,
	LOCATION_ERROR_SYSTEM,
} LocationGPSDControlError;

Enum representing reason for error why locationing is not available.

LocationGPSDControlPrivate

typedef struct _LocationGPSDControlPrivate LocationGPSDControlPrivate;

LocationGPSDControl

typedef struct _LocationGPSDControl LocationGPSDControl;

The object that controls the daemon processes. An application obtains an instance of this object by calling the location_gpsd_control_get_default() function.

location_gpsd_control_get_default ()

LocationGPSDControl* location_gpsd_control_get_default  (void);

This function is an alias for creating a new LocationGPSDControl object. This used to return a single instance of object, but not anymore as object properties cannot be shared between applications.

location_gpsd_control_start ()

void                location_gpsd_control_start         (LocationGPSDControl *control);

Starts an active connection to Location server. In other words, by calling this function the application informs that it wants to use the location service.

location_gpsd_control_stop ()

void                location_gpsd_control_stop          (LocationGPSDControl *control);

Informs the location framework that the application is no longer interested about the current location. Location service is kept running as long as there is at least one application using it. Please note that LocationGPSDevice still sends data as long as the location framework is running.

location_gpsd_control_request_status ()

void                location_gpsd_control_request_status
                                                        (LocationGPSDControl *control);

location_gpsd_control_get_allowed_methods ()

gint                location_gpsd_control_get_allowed_methods
                                                        (LocationGPSDControl *control);

This function reads current location settings and returns a bitmask of allowed location methods of type LocationGPSDControlMethod. Please note that you can also use methods, that are not currently allowed. Location Framework will in this case prompt user a dialog to enable necessary settings when location is started.

The "maincontext-pointer" property

  "maincontext-pointer"      gpointer              : Write

Set the main context address.

The "preferred-interval" property

  "preferred-interval"       gint                  : Read / Write

The interval between fixes the application prefers. The actual rate may be different.

Allowed values: >= -1

Default value: -1

The "preferred-method" property

  "preferred-method"         gint                  : Read / Write

The positioning method the application would like to use.

Allowed values: [0,15]

Default value: 0

The "error" signal

void                user_function                      (LocationGPSDControl *control,
                                                        gpointer             user_data)      : Run First / No Recursion

The ::error signal is emitted when location is stopped or not started due to error.

The "error-verbose" signal

void                user_function                      (LocationGPSDControl *control,
                                                        gint                 error,
                                                        gpointer             user_data)      : Run First / No Recursion

The ::error-verbose signal is a more verbose version of ::error signal, and is emitted when location is stopped or not started due to error.

The "gpsd-running" signal

void                user_function                      (LocationGPSDControl *control,
                                                        gpointer             user_data)      : Run First / No Recursion

The ::gpsd-running signal is emitted when location has been succesfully started.

The "gpsd-stopped" signal

void                user_function                      (LocationGPSDControl *control,
                                                        gpointer             user_data)      : Run First / No Recursion

The ::gpsd-stopped signal is emitted when location is stopped.
