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) }
