original structure inside the driver is as follows:
typedef struct _SHARED_EVENT
{
HANDLE hDnEvent;
HANDLE hUpEvent;
HANDLE unplugEvent;
HANDLE sysAssertEvent;
} SHARED_EVENT, *PSHARED_EVENT;
The HANDLE type inside the driver is platform speciefic, and
can be either 32bit or 64bit!
Since our DLL is assumed to be always compiled for 32bit platforms,
it is a problem.
Until the HANDLE types in the driver are changed to ULONG,
or until this DLL will have two diffrent barnches for 32bit and 64bit platforms,
the following Workarround is implemented:
1. Diffrent structs for 32bit and 64bit platforms.
2. when sending the IOCTL_OPEN_USER_MODE_EVENT, dynamically descide which struct to use.
