Get file status
resource eio_fstat ( mixed $fd, int $pri, callable $callback [, mixed $data ] )
eio_fstat() returns file status information in result argument of callback
Parameters:
fd
Stream, Socket resource, or numeric file descriptor.
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
Arbitrary variable passed to callback.
Returns:
eio_busy() returns request resource on success or FALSE on error.
Examples:
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();
?>
