Subject: [Xen-devel] [PATCH v2 8/9] libxl: Move qmp_parameters_* prototypes to libxl_internal.h
Date: Fri, 14 Jun 2019 11:38:00 +0100 [thread overview]
Message-ID: <20190614103801.22619-9-anthony.perard@citrix.com> (raw)
In-Reply-To: <20190614103801.22619-1-anthony.perard@citrix.com>
.. and rename them to libxl__qmp_param_*.
This is to allow other files than libxl_qmp.c to make QMP calls with
parameters.
