resource eio_busy ( int $delay [, int $pri = EIO_PRI_DEFAULT [, callback $callback = NULL [, mixed $data = NULL ]]] )

eio_busy() artificially increases load taking delay seconds to execute. May be used for debugging, or benchmarking.

delay: Delay in seconds
pri: Приоритет запросов: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, или NULL. Если передан NULL, то pri устанавливается в EIO_PRI_DEFAULT.
callback: This callback is called when all the group requests are done.
data: Arbitrary variable passed to callback.

eio_busy() returns request resource on success or FALSE on error.
