I want to calculate time elapsed during a function call in C, to the precision of 1 nanosecond.

Is there a timer function available in C to do it?

If yes please provide a sample code-snippet.

Pseudo code

Timer.Start()
foo();
Timer.Stop()
Display time elapsed in execution of foo()

Environment details: - using gcc 3.4 compiler on a RHEL machine

I need high-resolution (more accurate than 1 millisecond) timing in my application. The waitable timers in Windows are (or can be made) accurate to the millisecond, but if I need a precise periodicity of, say, 35.7142857141 milliseconds, even a waitable timer with a 36 ms period will drift out of… >>> More

Hi All. When reading data from a potentially slow website, I want to ensure that get_response can not hang, and so added a timer to timeout after x seconds. So far, so good. I then read http://ph7spot.com/musings/system-timer which illustrates that in certain situations timer.rb doesn't work due to… >>> More
