    eio_chown — Change file/directory permissions

    说明

    eio_chown(
        string $path,
        int $uid,
        int $gid = -1,
        int $pri = EIO_PRI_DEFAULT,
        callable $callback = NULL,
        mixed $data = NULL
    ): resource

    Changes file, or directory permissions.

    参数

    path

    Path to file or directory.

    警告

    避免相对路径。

    uid

    User ID. Is ignored when equal to -1.

    gid

    Group ID. Is ignored when equal to -1.

    pri

    请求的优先级：EIO_PRI_DEFAULT，EIO_PRI_MIN，EIO_PRI_MAX 或 null。如果是 null，pri 将设为 EIO_PRI_DEFAULT。

    callback

    callback 函数在请求完成时被调用。其应匹配一下原型：

    void callback(mixed $data, int $result[, resource $req]);
    data

    传递给请求的用户数据。

    result

    针对请求的结果的值。通常是相应的系统调用返回的值。

    req

    可选的请求资源，可被 eio_get_last_error() 之类的函数使用。

    data

    Arbitrary variable passed to callback.

    返回值

    eio_chown() returns request resource on success, 或者在失败时返回 false.
