Subject: [Qemu-devel] [PATCH v5 4/5] libqos: Add malloc generic
Date: Tue, 24 Feb 2015 22:21:54 +0100	[thread overview]
Message-ID: <1424812915-25728-5-git-send-email-marc.mari.barcelo@gmail.com> (raw)
In-Reply-To: <1424812915-25728-1-git-send-email-marc.mari.barcelo@gmail.com>

This malloc is a basic interface implementation that works for any platform.
It should be replaced in the future for a real malloc implementation for each
of the platforms.

Signed-off-by: Marc Marí <marc.mari.barcelo@gmail.com>
