WebGetTickCount是返回一个DWORD类型,其返回的值是自系统启动以来所经历的时间,单位:毫秒。 此段代码基本原理就是: 先GetTickCount取值赋于Start_Time,然后不停的循环用GetTickCount来和Start_Time来相减,直到这个差值大于参数DelayTime则退出循环结束过程,从而达到延时 ... WebApr 4, 2010 · Hello helpful C++ community, i'm new to these forums. Hope I get the format right...i've never tried adding code to a post and so on. I'm trying to create a simple time based solution where I can run my code (later) at specific time intervals. I thought it would be so simple. from using online searches and MSDN I came up with this code:
WebFrom MSDN. The resolution of the GetTickCount function is limited to the resolution of the system timer, which is typically in the range of 10 milliseconds to 16 milliseconds. The resolution of the GetTickCount function is not affected by adjustments made by the GetSystemTimeAdjustment function. The elapsed time is stored as a DWORD value. WebgetTickCount ()函数 VS GetTickCount ()函数. 这俩函数看上去长得太像了,笔者曾经马大哈地把两者当成一个函数了(确实长得很像),知道有一天发现返回的值离预期值差很远差仔细查了下。. 实际上,该函数为opencv中的函数,该函数返回的值为自从某一时刻(比如 ...
