No, BSD kernels have cmsgcred or so for it, which has much more
information then the Linux ucred struct (At least FreeBSD).

struct ucred should be definded in sys/socket.h.
Zack, for what do you need struct ucred ? Are you playing with
__SCM_CREDENTIALS in the moment ? I have some big problems with it,
which I couldn't solve. If I could see code which works, maybe
I could find my mistake.

Linux is like a Vorlon. It is incredibly powerful, gives terse,
cryptic answers and has a lot of things going on in the background.
