That's because it is in the source code tree.

You should call the IBM support number that you have.  They have been
asked this question a thousand times and have exactly the information
you are requesting.  The interface was initially not documented because
it wasn't to be used by user applications.  Obviously user's think it
is useful, so they are using it ;-)

Actually, if you have the process ID you have the slot number that the
(struct proc) is in.  You can take that number and use it as an offset
into the process table and read the entire structure yourself.  Of
course that's very unportable ...

This is another question for the FAQ for this group.  Is there anybody
collecting them this week???
