Thanks,
Anoop.

There are various profilers available......some compilers come with them

>Is there a C function that can calculate the CPU usage time for a process?

Code:

clock_t time_function ( void (*func_to_time)(void) )
{
  clock_t start, end;

  start = clock();
  /*
  ** Do some process.
  */
  func_to_time();
  end = clock();

  return end - start;
}

But keep in mind that a profiler is far more accurate. If your functions are quick then you will time them as 0 with this method.

Hey Prelude!: )...where can one find the definition of the clock() func and the data type clock_t?

cheers!

<time.h> or <ctime> if you are c++ inclined!
