event notification

Hello everybody.

I did a test, seems my event notification in the driver didn\'t wake up the
application each time.

In the driver I used:
////////////////////////////////////////////////////////////////
      if (gUserEvent!=NULL)
      {
       DbgPrint(\"Set Event: \\n\");

       ASSERT(KeGetCurrentIrql()<=DISPATCH_LEVEL);

       KeClearEvent(gUserEvent);

       KeSetEvent(gUserEvent, 0, FALSE);
      }
///////////////////////////////////////////////////////////

In the application I used:
///////////////////////////////////////////////////////////
    while(1)
    {
     status = WaitForSingleObject(api.m_hEvent, INFINITE);
     if (status == WAIT_ABANDONED || status == WAIT_OBJECT_0 || status ==
WAIT_TIMEOUT)
/* I used if (status == WAIT_OBJECT_0 ) the first time, the counts in the
application is less than the counts in the kernel, so I * changed to this
code */
     {
      printf(\"got event %d\\n\", api.k);
//      api.GetPacket();
//      api.GetPacket();
      api.k++;
     }
    }

///////////////////////////////////////////////////////////

still, the counts in the application is much less than the counts in kernel.

Any ideas? Thanks!

case closed. because kernel is too fast to set and clear the event, so the application lost some notifications.

我也遇到同样的问题了，驱动里面setevent太快，外面处理比较慢，怎么解决阿
