Examples

Example #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();
?>

The above example will output something similar to:

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)
}
