From the call hook, how do I know more precisely what is called?

[Vijay Kumar]

Hi,

I wrote a trace function using the profiling and tracing hooks
provided by the python interpreter.

The Python interpreter reports the calls occuring in the source
program to my trace function.

How can I know whether the call happened is a function call or method
call and if it is a method call what is its self object and/or  class
is?.

I receive a frame object from the interpreter for every call. 

Thanks,
Vijay.
