I was looking through some APIs and noticed these two. They both do the same thing, but which one is "better" to use? Please give your prefrences and reasons.

TimeGetTime() is portable on all platforms, standard in C(++?)
whereas GetTickCount() is M$ only. but they do the exact same thing.
Atleast that''s the only difference I know of. Did I miss something?

a couple of things.

first, timeGetTime is a win32 function, not a c one.

second, timeGetTime is much more accurate than GetTickCount (1 ms vs 50 ms resolution).

third, GetTickCount takes less time to execute.

fourth, nice use of the $. (stolen from Stoffel)

use GetTickCount if 50 ms resolution is acceptable because it has less overhead, and timeGetTime if you need more precise timing. remember to call timeBeginPeriod and timeEndPeriod to obtain 1 ms resolution on nt.

example: timeGetTime is a better choice if you want to calculate fps for your game, and GetTickCount will be better if you want to drop inactive clients from your game after let's say one minute timeout.
