The idea is that every API implementation in driver which has flags
parameter should first call virCheckFlags() macro to check the function
was called with supported flags:
virCheckFlags(VIR_SUPPORTED_FLAG_1 |
VIR_SUPPORTED_FLAG_2 |
VIR_ANOTHER_SUPPORTED_FLAG, -1);
The error massage which is printed when unsupported flags are passed
looks like:
invalid argument in virFooBar: unsupported flags (0x2)
Where the unsupported flags part only prints those flags which were
passed but are not supported rather than all flags passed.
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.
