Event Object
An event object is a synchronization object whose state can be explicitly
set to signaled by using RtSetEvent
or RtPulseEvent.
The two types of event objects are:
- Manual-reset
event — An event object whose state remains signaled until it is
explicitly reset to nonsignaled by RtResetEvent. While it is signaled,
any number of waiting threads, or threads that subsequently specify the
same event object in a call to RtWaitForSingleObject,
can be released.
- Auto-reset event
— An event object whose state remains signaled until a single waiting
thread is released, at which time the system automatically sets the state
to non-signaled. If no threads are waiting, the event object's state remains
signaled.
An event object is useful in sending a signal to a thread, indicating
that a particular action has occurred.
