* friends: INotificationService Implementation of GetEvent
According to the RE, the event isn't signaled when handle is returned.
```C
long nn::friends::detail::service::NotificationService::GetEvent(long this, uint *output_handle)
{
long inner_struct_event;
int result;
if (this->event_created)
{
inner_struct_event = &this->event_object;
}
else
{
inner_struct_event = &this->event_object;
result = CreateEvent(&this->event_object, 0, 1);
if ( result )
{
Assert();
}
this->event_created = true;
}
uint event_handle = nn::os::detail::DetachReadableHandleOfInterProcessEvent(inner_struct_event);
*output_handle = event_handle;
int unknown = *((char *)output_handle + 4);
*((char *)output_handle + 4) = 1;
if (unknown)
{
CloseHandle(*output_handle);
}
return 0LL;
}
```
