From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alex Bligh Subject: [PATCH 05/11] libxl_qmp: Introduces helpers to create an argument list. Date: Wed, 13 Feb 2013 18:32:14 +0000 Message-ID: <1360780340-19117-6-git-send-email-alex@alex.org.uk> References: <1360780340-19117-1-git-send-email-alex@alex.org.uk> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1360780340-19117-1-git-send-email-alex@alex.org.uk> List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: xen-devel , Stefano Stabellini Cc: Ian Jackson , Ian Campbell , Alex Bligh List-Id: xen-devel@lists.xenproject.org Those functions will be used to create a "list" of parameters that contain more than just strings. This list is converted by qmp_send to a string to be sent to QEMU. Those functions will be used in the next two patches, so right now there are not compiled.
