GetSystemTime, I think. CBF looking it up tho.

GetSystemTime(NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, 0);

no no, the time command in unix is used to measure program execution time.

Anyways, i just installed cygwin, so its all good.

The time utility executes and times the specified utility. After the utility finishes, time writes to the standard error stream, (in seconds): the total time elapsed, the time used to execute the utility process and the time consumed by system overhead.

wut NULL is defined in stdlib.h.

Apostrophe denotes ownership or omission, not plurality. Try harder.

Name: Anonymous 2007-07-10 5:00 ID:qczITofB

GetTickCount() isn't that accurate. For good performance measurements, use QueryPerformanceCounter.

Name: Anonymous 2007-07-10 5:11 ID:/pgC+9sN

Yeah sorry, I wasn't sure what the api was for 64bit time query. I guess there is :)

What's so ass-abrasive about QueryPerformanceCounter?

Name: Anonymous 2007-07-10 17:47 ID:qczITofB

>>21 It's a lil more work cause you have to use QueryPerformanceFrequency as well to calculate the elapsed time

>>30 brings up an interesting point. Most compilers will actually reserve stack space prior to the function call, and do simple mov instructions into the appropriate stack locations to load arguments. It's actually really cool.

That is interesting, I've never noticed that. Though probably because most programs I've disassembled have been built by MSVC, which pushes everything prior to a call.
