reading u blocks

[Paul Guthrie]

Could someone let me know how to read u-blocks on RT AIX 2.1?

I have tried seeking into /dev/mem from the address obtained
from the proc structure -> p_uptr.  This always yields the
same result, my *current* processes u block.  Do I have to 
grovel through the segment table?  Is there an easy way such
as a system call (like sysi86(RDUBLK) on 386/ix)?  There must
be some way..... ps works!

Thanks in advance,
