Parameters

path

Pathname of any file within the mounted file system

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)
}
