Detailed Description

Internal representation of the event handle (em_event_t) when using Event State Verification (ESV)

An event-generation-count is encoded into the high bits of the event handle to catch illegal usage after the event ownership has been transferred. Each user-to-EM event state transition increments the .evgen and thus obsoletes any further use of the handle by that user.
