It's not clear whether the program is attempting to determine it's
own (or a child's) memory footprint, or that of an arbitrary process.
In the former case, getrusage() is the obvious choice. This as a
portable interface.
If you want to examine arbitrary processes, the best interface on
FreeBSD would be kvm_getprocs(3).
BTW, since you mention heap objects, I presume you are aware that
malloc() uses mmap(), rather than sbrk() to obtain memory.
