This commit fixes qemu/qemu_driver.c: In function 'qemuDomainModifyDeviceFlags': qemu/qemu_driver.c:4041:8: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] qemu/qemu_driver.c:4013:9: note: 'ret' was declared here The variable is set to -1 so that the error paths are taken when the code to set it didn't get a chance to run. Without initializing it, we could return some an undefined value from this function. While I was at it, I made a trivial whitespace change in the same function to improve readability.
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.
