For each algorithm you may have an arbitrary number of drivers implementing it. The driver name must be unique. However, duplicates are allowed so that a new version of a driver may be loaded while the older instances of it are still in use. > But when I read the code, I often get confuse about these two names. > They often mix each other. > > Can you give me some instruction about them? or Can we make them more clear? Thanks. Well can you tell me what exactly confuses you?
