add milliseconds in c

Question

I am writing a code in c and I need to add milliseconds to the current time So far, i have :

current_time = time(NULL); loc_time=localtime(&current_time);

however this only gives HH:MM:SS when I need HH:MM:SS:MM

Say the local time is 20:00:00:10. I want to adding 10 milliseconds and display it so it displays 20:00:00:20. I am fairly new to c so any help is much appreciated. I am confused as time is of type int format and, to add milli seconds I will have to add .001 seconds to the current second which is not an int.

The problem is that "localtime()" API only has granularity of seconds (not milliseconds).

Try gettimeofday()

If you're on Windows, you can also try QueryPerformanceCounter():

How can I get the Windows system time with millisecond resolution?
