Well getrusage does actually exist in Linux, but its behaviour
isn't the same as on FreeBSD; struct rusage memory

In the former case, getrusage() is the obvious

Well, do you know that SIZE in top is virtual memory size, not resident

Yes, I do. So do you suggest using RES as a better

Almost certainly yes. Measuring virtual memory is significantly less
important for real-world loads. Some of this is very nicely described
here: https://www.varnish-cache.org/trac/wiki/ArchitectNotes .
definitely.
just run top and compare RES and SIZE fields.

I'd like to measure the memory footprint in C/C++ code for a

I think that it would be difficult to achieve the task

Linux, and do something else on FreeBSD.
I was adviced to have a look on getrusage, which I did, but I found
