 /**
+ * @deprecated Deprecated since 3.0.
  * @brief	Gets the absolute path to the application's shared data directory which is used to share
  *          data with other applications.
  * @details	An application can read and write its own files in the application's shared data
  *          directory and others can only read the files.
  * @since_tizen @if MOBILE 2.3 @elseif WEARABLE 2.3.1 @endif
- * @remarks	The returned path should be released.
+ * @remarks	The returned path should be released. @n
+ *		shared/data directory is not supported since Tizen 3.0.
+ *		You MUST NOT use this API when you develop new application.
+ *		Actually, we strongly recommend to stop using shared/data path for all your previous applications.
+ *		Files in shared/data directory can be read by all other applications.
+ *		You cannot control what applications can read the files in shared/data directory.
+ *		If you want to share files with other applications, consider passing path via @ref CAPI_APP_CONTROL_MODULE API.
+ *		The @ref CAPI_APP_CONTROL_MODULE API supports giving permission to other applications by passing path via app_control. @n
+ *		shared/data directory is only available for applications with api-version lower than 3.0 from Tizen 3.0 platform.
+ *		The applications with api-version from 3.0 cannot access other applications' shared/data directory.
+ *		For example, a Tizen 2.4 application can access another Tizen 2.4 application's shared/data directory as it did in Tizen 2.4 platform.
+ *		However, a Tizen 3.0 application cannot access another application's shared/data directory even the another application is Tizen 2.4 application.
+ *		Note that Tizen 3.0 platform only supports shared/data directory among applications with api-version lower than 3.0 for minimum backward compatibility. @n
+ *		The specific error code can be obtained using the get_last_result(). Error codes are described in Exception section.
