Implementers of an event handler
do not have to worry about the larger picture as it is dealt with by the event handling mechanism.
In these trigger states, invoking an event handler
costs no more than a function call, and no saving/restoring of CPU state is necessary.
They are more likely to be collections of event handlers
responding to your commands and other events arriving from outside the app itself.
This count in incremented each time the thread invokes an event handler
and decremented each time it returns.
Each individual event handler

Software development kit (SDK) - Ektron's second generation Application Programming Interface (API) and new Event Handler
Features such as the program monitor, the event handler
, and safe system shutdown cradle your application and make it resistant to external transient errors.
Plugin, Event Handler
and Custom Report Development: For an additional fee, GroundWork offers development, testing and certification of new Nagios plugins, event handlers
and custom reports.
For more advanced requirements, developers can use event handlers
to leverage existing application business logic or add special instructions at specific timing intervals.
The TVirtualDataSet component is data wrapper that doesn't store data in memory and interacts with data using event handlers
