[PATCH 1/7] libvirt.h: consolidate typed parameter handling

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

 



* include/libvirt/libvirt.h.in (virTypedParameterType)
(VIR_TYPED_PARAM_FIELD_LENGTH, _virTypedParameter): New enum,
macro, and type.
(virSchedParameter, virBlkioParameter, virMemoryParameter):
Rewrite in terms of a common type, while keeping all old public
names for backwards compatibility.
(struct _virSchedParameter, struct _virBlkioParameter)
(struct _virMemoryParameter): Delete - these are private names.
* python/generator.py (enum): Cope with the refactoring.
