What is used on Lion version for SMB sharing?

I know that Apple has chan开发者_如何学Goged implementation for SAMBA sharing on Lion Version. I am trying to share folder programmatically. IT works on Snow Leopard.

But it doesn't on Lion, can you give me a clue, what Apple used for SMB sharing on Lion version? And where does it store information about shared folders using SMB.

Here is a report from AppleInsider.

Apple has replaced SAMBA with their own proprietary internally-developed code, called SMBX, apparently largely due to not being able to comply with the SAMBA project's open-source licensing requirements.

I am not aware of any documentation released by Apple, but I don't have a developer account.
