The real problem with names and other string values is that you either need to copy the string or you expose internal data. If we copy the name, we can't make it part of the LayerDescription since that would mean that people would have to free it afterwards. We'd have to go for IDirectFBDisplayLayer::GetName() then. Your patch uses the GetName() API but it doesn't copy the string. Since it does not even mark it as const, people may try to free it. Since that would lead to some hard-to-debug problems later, I'd say we should return a copy instead.
