Measure execution time accurately

[mohsaied]

Hi all,

I am running some c++ code on linux and want to measure the exact amount of time it takes to run this code.

So far this has been working fine with the function clock.

double start = clock();

//some code

cout << "execution time = " << clock() - start << endl;

HOWEVER! Now that I have pthreads in my code, this function returns completely wrong results. How can I measure execution time in a different way so that it accounts for that?

thanks.
