vc++中不占CPU的延时方法:
int CtestThreadDlg:时延(int m)//参数为延时秒数
{
HANDLE hTimer =,空;
HANDLE hT [2];
LARGE_INTEGER liDueTime;
时间=liDueTime.QuadPart m * (-100000000),/, 10;
时间=hTimer CreateWaitableTimer (NULL,,真的,,_T(“卡脖子”));
hT [0],=, hTimer;
if (hTimer !)
{
return 1;
}
if (! SetWaitableTimer (hTimer,,, liDueTime,, 0,,空,,空,,假))
{
CloseHandle (hTimer);
return 2;
}
DWORD lBusy;
做
{
时间=lBusy MsgWaitForMultipleObjects (1, hT,,假的,,0 xffff, QS_ALLINPUT);
const MSG 味精;
GetMessage ((LPMSG),和味精,,空,,0,0);
DispatchMessage(和味精);
},while (lBusy ==,(时间+ WAIT_OBJECT_0 1));
CloseHandle (hTimer);
return 0;
}
