Since no value in the virGICVersion enumeration is negative, a clever
enough compiler can report an error such as
src/conf/domain_conf.c:15337:75: error: comparison of unsigned enum
expression < 0 is always false [-Werror,-Wtautological-compare]
if ((def->gic_version = virGICVersionTypeFromString(tmp)) < 0 ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~
virGICVersionTypeFromString() can, however, return a negative value if
the input string is not part of the enumeration, so we definitely need
that check.
Work around the problem by storing the return value in a temporary int
variable.
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.
