Hello Alessandro
My program also is in c.
In most C Compilers, there is a function called ftime
You have to include some file like "time.h" (see compiler)
program
#include <stdio.h>
#include <time.h>
#include <timeb.h>
main()
{
struct timeb tt;
long mytime;
ftime(&tt);
mytime=tt.time*1000+tt.millitm;
if you do this, you have the time in millisec in mytime as a start time
youse the same routinme sometimes else with another long variable and
the
difference is the ellapsed time.
I don´t know, if it helps you!
Best wishes
Werner
