EXAMPLES

       Example #1

	      eio_lstat(3) 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)
	      }
