How can you look at the u.area of another process?

[sanjay Radia]

We are creating a new kernel call that requires looking at the u. area
of another process (given its pid) in 4.2BSD.
Is there a convenient function in 4.2 to do this (we haven't been able
to find it)? Or has someone out there done something like this.

Thanks in advance.
