The virDBusMethodCall method has a DBusError as one of its parameters. If the caller wants to pass a non-NULL value for this, it immediately makes the calling code require DBus at build time. This has led to breakage of non-DBus builds several times. It is desirable that only the virdbus.c file should need WITH_DBUS conditionals, so we must ideally remove the DBusError parameter from the method. We can't simply raise a libvirt error, since the whole point of this parameter is to give the callers a way to check if the error is one they want to ignore, without having the logs polluted with an error message. So, we add a virErrorPtr parameter which the caller can then either ignore or raise using the new virReportErrorObject method. This new method is distinct from virSetError in that it ensures the logging hooks are run. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
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.
