This is one way. just myfunction() from myfunction.so will examine
the stack and associated modules.

I think I am much closer to finding my answer.  If I get the pid I can
look at /proc/pid/maps which tells me which modules are loaded and where.
Now I just need to get the stack from myfunction() to the top and see
where each function lands in the range that I have from /proc/pid/maps.  So 
my question is now only how do
I get the stack trace.  I need the address. I think I must write an assembly 
code to walk through the stack.
