I hope I didn't give the impression that there was a "standard" way to do 
it.  The code will be definitely system dependent.

It's been a while since I was on either a compiler or library team, so 
giving a hard example for any currently used architecture would be beyond 
my immediate abilities.  I do recall writing them, and that they were NOT 
difficult (on the same order as "stack unwinding", but probably simpler) 
and generally took one programmer somewhat less than a week given that the 
compiler team was available for all the 'dirty little details' about stack 
frames, etc.  Of course, these days, there are supporting databases to 
describe the contents of the frames (for the debuggers) which we'd want to 
use and that would likely up the programming effort required.
