종료할 때 EndEventCapture() 호출

StartEventCapture() 호출하면 WM_INPUT 메시지가 발생함

GetRawInputData를 사용해서 키보드, 마우스 이벤트를 가져오면 됨.

	RAWINPUTDEVICE rawInputDev[2];

	rawInputDev[0].usUsagePage = 0x01;
	rawInputDev[0].usUsage = 0x06;
	rawInputDev[0].dwFlags = RIDEV_INPUTSINK;
	rawInputDev[0].hwndTarget = GetSafeHwnd();

	//마우스 RAWINPUTDEVICE 구조체 설정
	rawInputDev[1].usUsagePage = 0x01;
	rawInputDev[1].usUsage = 0x02;
	rawInputDev[1].dwFlags = RIDEV_INPUTSINK;
	rawInputDev[1].hwndTarget = GetSafeHwnd();                 

	if( FALSE == RegisterRawInputDevices(rawInputDev, 2, sizeof(RAWINPUTDEVICE)) )
