Find the Perforce Label a workspace is synced to

I have a Perforce workspace which i开发者_如何学编程s synced with a p4 label specification. How do I find out which label has been synced here in my workspace.

I think you can't.

If you are trying to do this then I would imagine you are approaching something wrong. You should really be syncing to Changelists or if syncing to Labels then only briefly.
