Application-Defined Functions
To receive notice of provider events, you must write and install a notifier function. A notifier function is the callback function that a provider uses to communicate information back to your application for all events affecting a particular provider. A provider in asynchronous mode must have a notifier function to receive completion events.Most providers must also use a notifier function to retrieve asynchronous events. An endpoint provider can poll for asynchronous events using the
OTLookfunction, but a mapper provider or a service provider cannot poll for asynchronous events; it must use a notifier function instead. In general, it is recommended that all providers use notifier functions to handle both asynchronous and completion events.
