Creates a clipboard lock for sheet on port. Once a clipboard lock has been created, you can manipulate the clipboard contents safely. An instance of <clipboard> is returned, which is used to hold the clipboard contents.
You should not normally call open-clipboard yourself to create a clipboard lock. Use the macro with-clipboard to create and free the lock for you.
