Event Upcall

Each RAPI implementation must provide and document a mechanism to receive the incoming asynchronous RSVP events. Those systems which provide either the select() or poll() function must provide the mechanism described in Use with select() or poll() .

An upcall is invoked by the implementation's asynchronous event mechanism. It executes the function whose address was specified in the Event_rtn parameter in the rapi_session() call.

The event upcall function template rapi_event_rtn_t() is defined in reference manual page format, in the following pages.
