FWIW, "MuxChardev" sounds better to me. Not a big deal, though. (Also, I am not planning to touch any struct names for the sake of the new QOM declaration/definition macros. Renaming the type checking functions is enough churn.) > > > Imho, the QOM type name is mostly an internal detail, the C type name is > > dominant in the code. > > Err it is the reverse. The QOM type name is exposed public API via QOM > commands, while the C struct names are a internal private detail. I agree with Marc-André here. The C code is not just a detail. Code needs be easy to read, change and refactor. I'd really prefer to not have the external public API forcing a specific internal naming style. We have at least one case where it's probably going to be impossible to keep an exact match between the QOM type and type checker functions: "accel"/ACCEL. https://lore.kernel.org/qemu-devel/cafeaca9wejne5tfwggvwpubprkrs-a2-inc43xa_jbamaf9...@mail.gmail.com/ -- Eduardo
