Hmm.

/proc is a pseudo-file that maps complex in-memory kernal structures to an
easy-to-use set of files. It eliminates the need to understand
complex kernel structures, or to even know the location of the
structures.

When you say "How can I get it's location" - I'm not sure what you
want to do.  The memory manager maps virtual addresses into physical
addresses, and I am not sure you want the physical address. And
virtual addresses are relative to each process.

Get "what" location exactly? Do you want to know the exact contents of
the kernel memory?  Or do you want to know the exact contents of your
program in memory? The second is usually done with a debugger.

You could read the "proc" man page and examine /proc/$PID and see if
that helps.  I think a debugger is an easier approach, as it will help
you map variables in your source code to memory contents.
