The only reason why it isn't is that we don't ever pass the VIR_DOMAIN_CHR_DEVICE_TYPE_LAST as device type and that's very hard to infer. An option would be to remove the monstrosity called virDomainChrGetDomainPtrsInternal and friends and mabye produce a saner code that will be easier to introspect both for humans and compilers. > > Michal Privoznik (2): > apibuild: Substitute only pure number tokens > virSocketAddrIsPrivate: Work on 32bits platforms ACK to those two. This time I verified that I've applied the patch prior to trying to break it. Peter
