Public Member Functions

Event ()

virtual ~Event ()

void reset (void)

Once signaled, the Event class must be 'reset' before responding to a new signal. void signal (void)

Signal the event for the waiting thread. bool wait (timeout_t timer)

Wait either for the event to be signaled by another thread or for the specified timeout duration. bool wait (void)

The Event class implements a feature originally found in the WIN32 API; event notification.

A target thread waits on a resetable Event, and one or more other threads can then signal the waiting thread to resume execution. A timeout can be used to specify a wait duration in milliseconds. The Event class must be reset before it can be used again as a trigger. These event objects use a trigger/reset mechanism and are related to low level conditional variables.
