Hi, While working on OCEAN (yes, yes, we're still working on it :-) we have an annoying issue. We have some netname resolver tests that do work with the Squeak Mac VM 5.8, but they are not working in the Mac Cog VMs. This is because the following primitives are missing at the VM side. Still, they are useful cause they allow getting addresses of all network interfaces of your machine. primitiveResolverGetAddressInfo primitiveResolverGetAddressInfoSize primitiveResolverGetAddressInfoResult primitiveResolverGetNameInfo primitiveResolverGetNameInfoHostSize primitiveResolverGetNameInfoHostResult primitiveResolverGetAddressInfoNext There are methods defined in the old NetNameResolver (class side) that call these primitives, but they are NOT referenced. primGetAddressInfoHost:service:flags:family:type:protocol: primGetAddressInfoSize primGetAddressInfoResult: primGetNameInfo:flags: primGetNameInfoHostSize primGetNameInfoHostResult: primGetAddressInfoNext We checked the SqueakVM SVN, and they are there in the SocketPlugin.c Why didn't they get introduced in Mac CogVM? Are there missing for other platforms too? Luc and Noury -- http://twitter.com/#!/NouryBouraqadi
