Since all virTypedParameter APIs allow us to return the number of slots we actually populated, we should allow the user to call with nparams too small (without overrunning their array) or too large (ignoring the tail of the array that we can't fill), rather than requiring that they get things exactly right. Making this change will make it easier for a future patch to introduce VIR_TYPED_PARAM_STRING, with filtering in libvirt.c rather than in every single driver, since users already have to be prepared for *nparams to be smaller on exit than on entry. * src/qemu/qemu_driver.c (qemuDomainGetBlkioParameters) (qemuDomainGetMemoryParameters): Allow variable nparams on entry. (qemuGetSchedulerParametersFlags): Drop redundant check. (qemudDomainBlockStats, qemudDomainBlockStatsFlags): Rename... (qemuDomainBlockStats, qemuDomainBlockStatsFlags): ...to this. Don't return unavailable stats.
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.
