CAMEvent Class (Compact 2013)

3/26/2014

CAMEvent Class

This class is an event object that can be set and waited on to provide interthread synchronization.

This is currently implemented by using the Microsoft Win32® Event APIs.

Events can be created as manual-reset or automatic-reset, and will always be created as not set (nonsignaled state).

They can also be cast to handles so as to be passed to the Win32 WaitForMultipleObjects function.
