eio_stat — Get file status
eio_stat() returns file status information in
result argument of callback
pathThe file path
priThe 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]);datais custom data passed to the request.
resultrequest-specific result value; basically, the value returned by corresponding system call.
reqis optional request resource which can be used with functions like eio_get_last_error().
data
Arbitrary variable passed to callback.
eio_stat() returns request resource on success or
false on error. On success assigns result argument of
callback to an array.
Example #1 eio_stat() example
<?php
$tmp_filename = "eio-file.tmp";
touch($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($data);
}
eio_stat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_stat");
eio_open($tmp_filename, EIO_O_RDONLY, NULL,
EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
eio_event_loop();
?>Il precedente esempio visualizzerà qualcosa simile a:
