How to print milliseconds in C?

Question

I want to print time in the format hh:mm:ss:ms(milliseconds). I could print in the form of hh:mm:ss. What can be the way to print remaining milliseconds?

Answer 1

#include<sys/timeb.h>
#include<time.h>

int main(void) {
    struct timeb tp;
    ftime(&tp);
    char timeString[80];
    strftime(timeString, sizeof(timeString), "%H:%M:%S", localtime(&tp.time));
    printf("%s:%d", timeString, tp.millitm);
    return 0;
}

Answer 2

If you're working with the MSDN library, you could try

GetSystemTimeAsFileTime( pointerToSetToTime );

Which sets a pointer argument to the current system time in 100-nanosecond intervals.

Answer 3

This is what I use in linux ...

struct timeval tv;
gettimeofday(&tv,0);
time_t long_time;
struct tm *newtime;
time(&long_time);
newtime = localtime(&long_time);
char result[100] = {0};
sprintf(result, "%02d:%02d:%02d.%03ld", newtime->tm_hour,newtime->tm_min,newtime->tm_sec, (long)tv.tv_usec / 1000);
return result;

I have no experience working in windows .. try to find similar calls ..
