Question

I´m converting a Linux Logger to work in windows.
The logger prints with snprintf.
In linux, this logger output timeofday.tv_usec , that give something like this :

Jun 24 18:30:31-232928 test-transport...

In my windows version, using QueryPerformanceCounter, i generate results like this:

jun 24 23:54:18-866568508 test-transport....

In Linux, the uSeconds have exactly 6 digits, but this windows function generate 9 digits. How could i print only the 6 last digits ? Remember that this is a time critical code.

Answer 1

Use the remainder of dividing the number by 10 to the power of the number of digits you want to preserve.

In your case:

num % 1000000
