Hi all,
Is there any way of getting the system time, right down to the microsecond,
or even millisecond?

I need to do something a little like this:

int start_time=getTheTimeSomehow();     // Get the current time
doSomethingElse();                                 // Go and do something
else.
int end_time=getTheTimeSomehow()      // What's the time now?
int elapsed_time=end_time-start_time;     // How long did it take?

And I need to know the time as accurately as possible.


I would expect there to be a function somewhere, but I just don't know
where.

gettimeofday() is one such method.

clock_gettime is intended to go down to the nanoseconds.
