find out previous caller

Question

assuming the following scenario:

a user A calls a function in contract CA which in turn calls a function in contract CB which call a function in contract CC

I would like to discover who called CB within CC. User a is the tx.origin. Is there a way to get the call stack from within a function?

No, unfortunately Solidity can't provide the caller of the caller.

If you control CB you could of course have it pass its msg.sender as a parameter of its call to CC.
