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();
?>

string(17) "/tmp/eio-file.tmp"
array(11) {
  ["f_bsize"]=>
  int(4096)
  ["f_frsize"]=>

  ["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"]=>
