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.
