Way back when I started making changes for Coverity messages my first set were to a bunch of CHECKED_RETURN errors. In particular virAsprintf() had a few callers that Coverity noted didn't check their return (although some did check if the buffer being printed to was NULL or not). It was suggested at the time as a further patch an ATTRIBUTE_RETURN_CHECK should be added to virAsprintf(), see: https://www.redhat.com/archives/libvir-list/2013-January/msg00120.html This patch does that and fixes a few more instances not found by Coverity that failed the check.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
