Well
as the headline refere: does any one have a way to time you code , since i need one ( both on windows, but also on RHW( no os ))

Use the RDTSC instruction.

It has some pitfalls though, but its pretty much the only OS independent trick you can do.

Code: Select all

#include <ctime>
#include <iostream>
 
using namespace std;
 
class timer
{
public:
    timer() : start(clock()) { }
    ~timer();
private:
    clock_t start;
};
 
inline timer::~timer()
{
    cout << "timer took "<< double(clock()-start)/CLOCKS_PER_SEC
        << " seconds" << endl;

}

Altough it requires C++ and the C++Lib.

Check here: http://en.wikipedia.org/wiki/RDTSC

Also their external link right at the bottom which reads: "cycle.h - C code to read the high-resolution timer on many CPUs and compilers."

Did you even look in to Combuster's response, which was direct and to the point?
