How to query a function and get a list of expected parameters?

I'm writing a function that accepts a function as an argument, and I
want to know to all the parameters that this function expects.  How can
I find this out in my program, not by reading the source?

For example, I would want to know for the function below that I have to
pass in two things:

def f(x1, x2): return x1 * x2

It would be nice to get the names also.

All help is welcome.

TIA

Matt
