[PATCH v3 3/9] qemu_monitor_json: Move InetSocketAddress build to a separate function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, we are building InetSocketAddress qemu json type
within the qemuMonitorJSONNBDServerStart function. However, other
future functions may profit from the code as well. So it should
be moved into a static function.
