    eio_fstat — Get file status

    Açıklama

    eio_fstat(
        mixed $fd,
        int $pri,
        callable $callback,
        mixed $data = ?
    ): resource

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

    Bağımsız Değişkenler

    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(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.

    Dönen Değerler

    eio_busy() returns request resource on success, başarısızlık durumunda false döner.

    Örnekler

    Örnek 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();
    ?>

    Yukarıdaki örnek şuna benzer bir çıktı üretir:

    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)
}
