eio_stat — Get file status

### Description

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:

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

    is custom data passed to the request.

  `result`

    request-specific result value; basically, the value returned by corresponding system call.

  `req`

    is optional request resource which can be used with functions like eio_get_last_error()

`data`

  Arbitrary variable passed to `callback`.

### Return Values

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

### Examples

Example #1 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)
    }
