Coverity already saw through a NULL dereference without these annotations, and gcc is still too puny to do good NULL analysis. But clang still benefits (and is easier to run than coverity), not to mention that adding this bit of documentation to the code may help future developers remember the constraints. * src/util/uuid.h (virGetHostUUID, virUUIDFormat): Document restrictions, for improved static analysis.
