How to get the time elapsed in C in milliseconds? (Windows)

I've searched in the Web but I've only found a way for do it, but in this way it returns in seconds instead of milliseconds.

My code is:

#include <stdio.h>
#include <assert.h>
#include <time.h>

int main(void)
{
    int solucion;

    time_t start, stop;
    clock_t ticks;
    long count;

    time(&start);
    solucion = divisores_it(92000000, 2);
    time(&stop);

    printf("Finnished in %f seconds. \n", difftime(stop, start));
    return 0;
}

A cross platform way is to use ftime.

Windows specific link here: http://msdn.microsoft.com/en-us/library/aa297926(v=vs.60).aspx

Example below.

#include <stdio.h>
#include <sys\timeb.h> 

int main()     
{ 
    struct timeb start, end;
    int diff;
    int i = 0;
    ftime(&start);

    while(i++ < 999) {
        /* do something which takes some time */
        printf(".");    
    }

    ftime(&end);
    diff = (int) (1000.0 * (end.time - start.time)
        + (end.millitm - start.millitm));

    printf("\nOperation took %u milliseconds\n", diff);
    return 0;
}

I ran the code above and traced through it using VS2008 and saw it actually calls the windows GetSystemTimeAsFileTime function.

Anyway, ftime will give you milliseconds precision.
