+ * @brief Retrieves direct dependencies of the given package.
+ * @details package_info_dependency_info_cb() is called for each direct dependency of the given package.
+ *          For example, if there are packages having the following relationship:
+ *
+ * <pre>
+ *                B --> E
+ *          A --> B --> C
+ *                D --> C
+ * </pre>
+ * A --> B means that A depends on B.
+ *
+ * If package_archive_info_foreach_direct_dependency(A) is called, the callback will be called once with the following argument values: @e from = A, @e to = B.
+ * @since_tizen 5.5
+ * @remarks The function provides the results synchronously. If there are no dependencies, this function will return PACKAGE_MANAGER_ERROR_NONE immediately and the callback will not be invoked.
+ * @param[in] archive_info The package archive information
+ * @param[in] callback     The iteration callback function
+ * @param[in] user_data    The user data to be passed to the callback function
+ * @return @c 0 on success,
+ *         otherwise a negative error value
+ * @retval #PACKAGE_MANAGER_ERROR_NONE              Successful
+ * @retval #PACKAGE_MANAGER_ERROR_INVALID_PARAMETER Invalid parameter
+ * @retval #PACKAGE_MANAGER_ERROR_SYSTEM_ERROR      Severe system error
