 basefile - хэндл файла (к которому применимы функции read и seek из kfar_info)
-name - имя файла (во временном буфере)
 attr - указатель на структуру с атрибутами файла в формате системной функции 70.1
 data - буфер, содержащий данные из начала файла (может использоваться для определения типа файла)
 datasize - размер данных в data. В текущей реализации min(1024,размер файла)
