    eio_statvfs — Get file system statistics

    Description

    eio_statvfs(
        string $path,
        int $pri,
        callable $callback,
        mixed $data = ?
    ): resource

    eio_statvfs() returns file system statistics information in result argument of callback

    Parameters

    path

    Pathname of any file within the mounted file system

    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_statvfs() returns request resource on success, or false on failure. On success assigns result argument of callback to an array.

    Examples

    Example #1 eio_statvfs() example

    <?php$tmp_filename = '/tmp/eio-file.tmp';touch($tmp_filename);function my_statvfs_callback($data, $result) {    var_dump($data);    var_dump($result); @unlink($data);}eio_statvfs($tmp_filename, EIO_PRI_DEFAULT, "my_statvfs_callback", $tmp_filename);eio_event_loop();?>

    The above example will output something similar to:

    string(17) "/tmp/eio-file.tmp"
array(11) {
  ["f_bsize"]=>
  int(4096)
  ["f_frsize"]=>
  int(4096)
  ["f_blocks"]=>
  int(262144)
  ["f_bfree"]=>
  int(262111)
  ["f_bavail"]=>
  int(262111)
  ["f_files"]=>
  int(1540815)
  ["f_ffree"]=>
  int(1540743)
  ["f_favail"]=>
  int(1540743)
  ["f_fsid"]=>
  int(0)
  ["f_flag"]=>
  int(4102)
  ["f_namemax"]=>
  int(255)
}
