VC++中不占CPU的延時方法:
int CtestThreadDlg::DelayTime(int m)//參數為延時秒數 { HANDLE hTimer = NULL; HANDLE hT[2]; LARGE_INTEGER liDueTime; liDueTime.QuadPart = m *(-100000000) / 10; hTimer = CreateWaitableTimer(NULL, TRUE, _T("theTimer")); hT[0] = hTimer; if (!hTimer) { return 1; } if (!SetWaitableTimer(hTimer, &liDueTime, 0, NULL, NULL, FALSE)) { CloseHandle(hTimer); return 2; } DWORD lBusy; do { lBusy = MsgWaitForMultipleObjects(1, hT, FALSE, 0xffff, QS_ALLINPUT); const MSG msg; GetMessage((LPMSG) &msg, NULL, 0, 0); DispatchMessage(&msg); } while (lBusy == (WAIT_OBJECT_0 + 1)); CloseHandle(hTimer); return 0; }
