[Qemu-devel] [RFC 3/3] qapi: provide send/bcast interface for events |
|
Date: |
Wed, 4 Jul 2018 17:10:38 +0800 |
In the past we were always sending events to all the monitors. In this
patch we introduce a new interface to send an event to a specific
monitor instance, meanwhile renaming the old function from "send" to
"bcast". So for each event, now we have:
- qapi_event_send_xxx(Monitor *mon, ...) to send events to a monitor, or
- qapi_event_bcast_xxx(...) to send events to all the monitors.
