eio_stat

(PECL eio >= 0.0.1dev)

Get file status

resource eio_stat ( string $path, int $pri, callable $callback [, mixed $data = NULL ] )

eio_stat() returns file status information in result argument of callback

Parameters:

path

The file path

pri

The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or NULL. If NULL passed, pri internally is set to EIO_PRI_DEFAULT.

callback

callback function is called when the request is done. It should match the following prototype:

1	`void callback(mixed` `$data, int` `$result[, resource` `$req]);`

data

Arbitrary variable passed to callback.

Returns:

eio_stat() returns request resource on success or FALSE on error. On success assigns result argument of callback to an array.

Examples:

eio_stat() example

<?php
$tmp_filename = "eio-file.tmp";
touch($tmp_filename);
 
function my_res_cb($data, $result) {
    var_dump($data);
    var_dump($result);
}
 
function my_open_cb($data, $result) {
    eio_close($result);
    eio_event_loop();
 
    @unlink($data);
}
 
eio_stat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_stat");
eio_open($tmp_filename, EIO_O_RDONLY, NULL,
 EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
eio_event_loop();
?>

The above example will output something similar to:

string(8) "eio_stat"
array(12) {
  ["st_dev"]=>
  int(2050)
  ["st_ino"]=>
  int(2489173)
  ["st_mode"]=>
  int(33188)
  ["st_nlink"]=>
  int(1)
  ["st_uid"]=>
  int(1000)
  ["st_gid"]=>
  int(100)
  ["st_rdev"]=>
  int(0)
  ["st_blksize"]=>
  int(4096)
  ["st_blocks"]=>
  int(0)
  ["st_atime"]=>
  int(1318250380)
  ["st_mtime"]=>
  int(1318250380)
  ["st_ctime"]=>
  int(1318250380)
}
