dx::log Union Reference

the whole log setting in one 32 bit word: a dx::log::level per dx::log::scope per dx::log::module, four bits each. The word is what a driver, a kernel and a host exchange and compare; the named members are the same bits, and to/from name them for a preference, a command line or a property. The serialization macros hand the member list to the tree and CF sinks of dx_serialize.h, so the store holds the log resolved rather than the word. More...
