## Description

GeoclueGeocode contains geocoding methods. It is part of the Geoclue public C client API which uses D-Bus to communicate with the actual provider.

After a GeoclueGeocode is created with `geoclue_geocode_new()`, the `geoclue_geocode_address_to_position()`, `geoclue_geocode_freeform_address_to_position()` methods and their asynchronous counterparts can be used to obtain the position (coordinates) of the given address.

Address GHashTable keys are defined in

geoclue-types.h. See also

convenience functions in

geoclue-address-details.h.

## Functions

### geoclue_geocode_new ()

    GeoclueGeocode *
    geoclue_geocode_new (const char *service,
                         const char *path);

Creates a GeoclueGeocode with given D-Bus service name and path.

#### Parameters

service | D-Bus service name |
path | D-Bus path name |

#### Returns

Pointer to a new GeoclueGeocode

### geoclue_geocode_address_to_position ()

    GeocluePositionFields
    geoclue_geocode_address_to_position (GeoclueGeocode *geocode,
                                         GHashTable *details,
                                         double *latitude,
                                         double *longitude,
                                         double *altitude,
                                         GeoclueAccuracy **accuracy,
                                         GError **error);

Geocodes given address to coordinates (`latitude` , `longitude` , `altitude` ). see geoclue-types.h for the hashtable keys usable in `details` . `accuracy` is a rough estimate of the accuracy of the returned position.

If the caller is not interested in some values, the pointers can be left `NULL`.

#### Parameters

geocode | A GeoclueGeocode object |
details | Hashtable with address data |
latitude | Pointer to returned latitude in degrees or `NULL` |
longitude | Pointer to returned longitude in degrees or `NULL` |
altitude | Pointer to returned altitude in meters or `NULL` |
accuracy | Pointer to returned GeoclueAccuracy or `NULL` |
error | Pointer to returned Gerror or `NULL` |

#### Returns

A GeocluePositionFields bitfield representing the validity of the returned coordinates.

### GeoclueGeocodeCallback ()

    void
    (*GeoclueGeocodeCallback) (GeoclueGeocode *geocode,
                               GeocluePositionFields fields,
                               double latitude,
                               double longitude,
                               double altitude,
                               GeoclueAccuracy *accuracy,
                               GError *error,
                               gpointer userdata);

Callback function for the asynchronous methods.

#### Parameters

geocode | A GeoclueGeocode object |
fields | A GeocluePositionFields bitfield representing the validity of the position values |
latitude | Latitude in degrees |
longitude | Longitude in degrees |
altitude | Altitude in meters |
accuracy | Accuracy of measurement as GeoclueAccuracy |
error | Error as Gerror or `NULL` |
userdata | User data pointer |

### geoclue_geocode_address_to_position_async ()

    void
    geoclue_geocode_address_to_position_async
                                   (GeoclueGeocode *geocode,
                                    GHashTable *details,
                                    GeoclueGeocodeCallback callback,
                                    gpointer userdata);

Function returns (essentially) immediately and calls `callback` when the geocoded position data is available or when D-Bus timeouts.

see geoclue-types.h for the hashtable keys usable in `details` .

#### Parameters

geocode | A Geocluegeocode object |
details | A GHashTable with address data |
callback | A GeoclueAddressCallback function that should be called when return values are available |
userdata | pointer for user specified data |

    GeocluePositionFields
    geoclue_geocode_freeform_address_to_position
