Those symbols may not exist in the SYSV-based PTX kernel's name list.  The
"nproc" symbol is often replaced by the v_proc element of the var structure
(see <sys/var.h>), usually named "v" by the kernel.

I don't know how PTX defines and addresses the process table.  You might be
able to find out by running nm on /dynix or /unix or /vmunix or whatever PTX
calls the kernel file and looking for symbols with "proc" in them.  Look for
variants, too, like "_proc" -- DYNIX 3.0.x uses it and "_nproc".

Discovering the way a kernel describes its process table is always an
adventure.  You should look for special functions to read the process (and
even user) table.  SGI IRIX, for example, has syssgi; and SunOS, of course,
has the kvm_* functions.

Finally, you might try porting lsof instead of ofiles.  Lsof (for LiSt Open
Files) is my version of a multi-platform ofiles successor.  It's available
via anonymous ftp from ftp.cc.purdue.edu (128.210.24.1) in pucc/lsof2.tar.Z.
