Functions
| Name | Description |
|---|---|
| Location_BasicInfo OH_LocationInfo_GetBasicInfo (Location_Info *location) | Obtains basic location information. |
| Location_ResultCode OH_LocationInfo_GetAdditionalInfo (Location_Info *location, char *additionalInfo, uint32_t length) | Obtains the additional information in the location information. |
| Location_RequestConfig * OH_Location_CreateRequestConfig (void) | Creates a Location_RequestConfig instance. |
| void OH_Location_DestroyRequestConfig (Location_RequestConfig *requestConfig) | Destroys the Location_RequestConfig instance and reclaims the memory. |
| void OH_LocationRequestConfig_SetUseScene (Location_RequestConfig *requestConfig, Location_UseScene useScene) | Sets the use scene in the location request configuration. useScene takes precedence over powerConsumptionScene in Location_RequestConfig. If useScene is set, powerConsumptionScene is invalid. Otherwise, powerConsumptionScene takes effect. If neither of the two parameters is set, useScene is set to LOCATION_USE_SCENE_DAILY_LIFE_SERVICE by default, and powerConsumptionScene is invalid. |
| void OH_LocationRequestConfig_SetPowerConsumptionScene (Location_RequestConfig *requestConfig, Location_PowerConsumptionScene powerConsumptionScene) | Sets the power consumption scene in the location request configuration. |
| void OH_LocationRequestConfig_SetInterval (Location_RequestConfig *requestConfig, int interval) | Sets the location reporting interval in the location request configuration. |
| void OH_LocationRequestConfig_SetCallback (Location_RequestConfig *requestConfig, Location_InfoCallback callback, void *userData) | Sets the callback function. |
