Finding total memory used and elapsed real-time

[CalicoKitty]

I'm writing a program that analyzes several algorithms and need to find out how much memory is used and how much real-time has elapsed. Can I just use sbrk(0) before and after each algorithm to analyze the memory usage? Does anybody have any suggestions for the elapsed real-time usage? I can find CPU time. It's unbelievable how the small things can hang a programmer up!

I don't know if you need better data, but the shell builtin "time" might come in very handy. No memory information, but there are plenty of other proc tools for that.

It just occured to me that you may not be using a *NIX. If that's the case, shame on you.

>time ls
.somefiles morefiles etc
real 0m0.160s
user 0m0.050s
sys 0m0.080s
