WebMar 31, 2024 · 在精度要求较高的情况下,可以利用GetTickCount()函数,该函数的返回值是 DWORD型,表示以ms为单位的计算机启动后经历的时间间隔(最大49.7天)。 在较短的定时中其计时误差为15ms,在较长的定时中其计时误差较低,如果定时时间太长,就好象死机一样,CPU占用率 ... WebZwGetTickCount() is used the same way as GetTickCount(). Using KiGetTickCount() is faster than calling ZwGetTickCount(), but slightly slower than reading from the KUSER_SHARED_DATA page directly.

WebAug 28, 2004 · GetTickCount to get elapsed time in ms. The same test harness was used for both GDI+ and GDI. To make the comparsion as fair as possible, I requested GDI+ to render at highest speed at the expense of quality. Is this GDI+ slowness problem incurable. I wonder? Any ideas/opinons/cures/refutations? Here is (most of) the benchmark program: http://haodro.com/archives/7474 WebJun 30, 2014 · GetTickCount () is a monotonic timer that increments at fixed intervals without any adjustments while GetLocalTime () is a real time clock that is affected by adjustments (Windows may detect an inaccuracy and add small offsets at each tick or even synchronize the clock with other time sources like NTP). dewetting process
