How does one call different functions when using multiprocessing?

All the examples I have looked at, define a function to call as a separate process. But each of the functions are self contained - they do not call any other functions, and at best receive a "queue" object as a parameter.

Does that mean that each process that is created can call other functions in the file by default, and the function that is passed to create the process is just how to start the process ? Can anyone show me how to call different functions in the same file ?
