Thu Sep 22 20:42:47 UTC 2011
Networking definitions. Fixing this involved some refactoring of
common code out of domain_conf and nwfilter_conf into nwfilter_params.
* src/conf/nwfilter_params.h (virNWFilterFormatParamAttributes):
Adjust signature.
* src/conf/nwfilter_params.c (_formatParameterAttrs)
(virNWFilterFormatParamAttributes): Adjust indentation.
* src/conf/domain_conf.c (virDomainNetDefFormat)
(virDomainActualNetDefFormat): Add parameter.
(virDomainDefFormatInternal): Adjust caller.
* src/conf/nwfilter_conf.c (virNWFilterIncludeDefFormat): Likewise.
