These are the platform support files for running mDNSCore on VxWorks. Please note, most of the developers working on the mDNSResponder code do not have access to a VxWorks development environment, so they are not able to personally verify that the VxWorks compiles and runs successfully after every single change to the mDNSCore code. We do try to take care not to make careless changes that would break the VxWorks build, but if you do find that something is broken, let us know and we'll fix it.
