Determine Process Info Programmatically in Darwin/OSX

Question

I have a class with the following member functions:

/// caller pid
virtual pid_t Pid() const = 0; 

/// physical memory size in KB
virtual uint64_t Size() c         


        

Answer 1

Most of this info can be gotten from GetProcessInformation().

By the way, why virtual methods for functions that return processwide info?

This is CARBON only, and won't work with cocoa
