    eio_lstat — Get file status

    Description

    eio_lstat(
        string$path,
        int$pri,
        callable$callback,
        mixed$data = NULL
    ): resource

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

    Parameters

    path

    The file path

    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.

    req

    is optional request resource which can be used with functions like eio_get_last_error()

    data

    Arbitrary variable passed to callback.

    Return Values

    eio_lstat() returns request resource on success or false on error.

    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) }
