Vaa3D_内存、运行时间统计_windows

windows系统下，包含Windows.h和Psapi.h即可调用api获取尖峰内存消耗等信息。

可以自己修改内存、时间等的记录单位。
用法是通过addCheckPoint函数，记录当前占用的内存和运行的时间。
数据会被记录在 timePoint memoryPoint; zhushi; 这三个vector变量中。

然后在程序结束以后，通过print2File函数将记录的信息输出到文件中。
print2File这个函数可以根据自己的需要进行一定的修改。

MemoryTimeCount mt_count;
mt_count.addCheckPoint("prepare");mt_count.print2File(QString filename);

#include "memorytimecount.h"MemoryTimeCount::MemoryTimeCount()
{//需要记录的内容有   程序的起始时间   time=time.currentTime();time.start();PeakWorkingSetSize=0;WorkingSetSize=0;PeakPagefileUsage=0;PagefileUsage=0;PrivateUsage=0;LogCurrentProcessMemoryInfo();
}

注意

这个头文件的顺序不能改变，否则有可能发生变异错误
