求助（DriverWorks中的KEvent用法）

DriverWorks中的KEvent用法。
作用。

其实很简单的。你想知道什么呢？先贴个我自己实现的例子。

KEvent * m_pMicrosecondEvent;

switch(I.IoctlCode())

case IVRDRIVER_IOCTL_HookMicrosecondEvent:
{
   HANDLE hMSecondEvent = *(HANDLE *)I.IoctlBuffer();
   if(hMSecondEvent == NULL)
   {
       t << "Handle is null\n";
       I.Information() = 0;
       status = STATUS_INSUFFICIENT_RESOURCES;
       break;
   }
   if(m_pMicrosecondEvent != NULL)
   {
delete m_pMicrosecondEvent;
m_pMicrosecondEvent = NULL;
   }
   m_pMicrosecondEvent =
       new (NonPagedPool)  KEvent (hMSecondEvent,
                 OBJECT_TYPE_ALL_ACCESS);

   if(m_pMicrosecondEvent != NULL)
   {
I.Information() = sizeof(UCHAR);
*(UCHAR *)I.IoctlBuffer() = 1;
status = STATUS_SUCCESS;
t << "Succed in connect OneSecond event\n";
    }
    else
    {
I.Information() = sizeof(UCHAR);
*(UCHAR *)I.IoctlBuffer() = 0;
           status = STATUS_SUCCESS;
    }
}
break;

m_pMicrosecondEvent->Pulse();//手动
m_pMicrosecondEvent->Set();//自动

应用层调用
HANDLE MicrosecondEvent = CreateEvent(NULL,FALSE,FALSE,NULL);//自动
HANDLE MicrosecondEvent = CreateEvent(NULL,TRUE,FALSE,NULL);//手动

DeviceIoControl(m_hDevice,
IVRDRIVER_IOCTL_HookMicrosecondEvent,
&MicrosecondEvent,
sizeof(MicrosecondEvent),
&returnvalue,
sizeof(UCHAR),
&nOutput,
NULL)

我也是这样做的
为何 总是死机呢
