ISC Unix 2.2 nlist Help/Where's adb?

[Adnan Yaqub]

I am trying to write a program which reads values from /dev/kmem.  The
program works great except when I try to lseek to the value returned
by nlist, lseek bombs (returns -1, errno 0).  The values nlist gives
me are like 0xd00011e4.  This, I suppose, looks like a negative number
to lseek (which wants a long, not unsigned long, offset according to
the manual) and it doesn't like that.  Any ideas how this is supposed
to work?

On a related topic, what happened to adb?  It didn't seem to come with
ISC Unix 2.2.

Thanks.
