+              Note that this API returns success only when there is no configuration enabled
+              about maximum touch count in the display server.
+   * @param[in] max_count The maximum number of touches want to generate.
+   * @return @c 0 on success, otherwise a negative error value
+   * @retval #EFL_UTIL_ERROR_NONE Successful
+   * @retval #EFL_UTIL_ERROR_INVALID_PARAMETER Invalid parameter
+   * @retval #EFL_UTIL_ERROR_PERMISSION_DENIED Has no permission to deinitialize input generator
+   * @retval #EFL_UTIL_ERROR_NO_RESOURCE_AVAILABLE Resource is not available
