# eio_fstat

(PECL eio >= 0.0.1dev)

eio_fstat — Get file status

### Beschreibung

resource eio_fstat ( mixed `$fd` , int `$pri` , callable `$callback` [, mixed `$data` ] )

eio_fstat() returns file status information in `result` argument of `callback`

### Parameter-Liste

`fd`

  Stream, Socket resource, or numeric file descriptor.

`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:

  `void callback($data, $result);`
  `$data` is custom data passed to the request. `$result` contains request-specific result value; basically, the value returned by corresponding system call.
`data`

  Arbitrary variable passed to `callback`.

### Rückgabewerte

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

### Beispiele

Beispiel #1 eio_lstat() example

`<?php
// Create temporary file
$tmp_filename = dirname(__FILE__) ."/eio-file.tmp";
touch($tmp_filename);
/* Is called when eio_fstat() done */
function my_res_cb($data, $result) {
// Should output array with stat info
var_dump($result);
if ($data['fd']) {
// Close temporary file
eio_close($data['fd']);
eio_event_loop();
}
// Remove temporary file
@unlink($data['file']);
}
/* Is called when eio_open() done */
function my_open_cb($data, $result) {
// Prepare data for callback
$d = array(
'fd' => $result,
'file'=> $data
);
// Request stat info
eio_fstat($result, EIO_PRI_DEFAULT, "my_res_cb", $d);
// Process request(s)
eio_event_loop();
}
// Open temporary file
eio_open($tmp_filename, EIO_O_RDONLY, NULL, EIO_PRI_DEFAULT,
"my_open_cb", $tmp_filename);
eio_event_loop();
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    array(12) {
     ["st_dev"]=>
      int(2050)
      ["st_ino"]=>
      int(2489159)
      ["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(1318239506)
      ["st_mtime"]=>
      int(1318239506)
      ["st_ctime"]=>
      int(1318239506)
    }
