function time

[afpr]

I need a function to get time(seconds and microseconds) in windows, like gettimeofday in Linux. Can you help me? Thanks

GetSystemTime()

I need to get the microseconds too. What is the function, if exists? thanks

[led mike]

Opps sorry, I saw milliseconds. I don't know if microseconds are supported.

Windows does not have that level of resolution. What exactly are you trying to do?

You might want to look at this http://www.codeproject.com/datetime/perftimer.asp[^] and this http://www.codeproject.com/datetime/ccputicker.asp[^]

Check ::GetSystemTimeAsFileTime() in the MSDN library.

I have found a solution. Use this functions: /* Initialize everything to 0 */ void sec_init(void) { LARGE_INTEGER lFreq, lCnt; QueryPerformanceFrequency(&lFreq); freq = (double)lFreq.LowPart; QueryPerformanceCounter(&lCnt); start = lCnt.LowPart; } /* return number of seconds since sec_init was called with ** a gross amount of detail */ double sec(void) { LARGE_INTEGER lCnt; long tcnt; QueryPerformanceCounter(&lCnt); tcnt = lCnt.LowPart - start; return ((double)tcnt) / freq; }
