[PATCH 40/68] qemu: Generalize macro for getting VIR_MIGRATE_* typed params

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



So far it's used only for CPU throttling parameters which are all ints,
but we'll soon want to use it for more parameters with different types.
