how to get elapsed time?

I am writting in c++ and i want to know how much time has elapsed while executing some part of code. In windows I would use GetTickCount() like this:

time=GetTickCount();
//some code
time=GetTickCount()-time;
printf("Time elapsed: %d",time);

What function can I use in linux? The function doesn't have to be portable but it must have at least millisecond resolution.

Re: how to get elapsed time?

take a look at 'man clock_gettime' and 'man gettimeofday'
