): resource

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

Parameters

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.

Examples

Example #1 eio_lstat() example

<?php
$tmp_filename
= dirname(__FILE__). "/eio-file.tmp";
touch($tmp_filename);

function
my_res_cb($data, $result) {
var_dump($data);
var_dump($result);
}

function
my_open_cb($data, $result) {
eio_close($result);
eio_event_loop();

@
unlink($data);
}

eio_lstat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_lstat");
eio_open($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:

string(9) "eio_lstat"
array(12) {
 ["st_dev"]=>
  int(2050)
  ["st_ino"]=>
  int(2099197)
  ["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(1318235777)
  ["st_mtime"]=>
  int(1318235777)
  ["st_ctime"]=>
  int(1318235777)
}
