[pacman-dev] alpm_list_* functions : public or private ?

The functions in alpm_list.c all start with alpm_list_, but some of them don't have SYMEXPORT. By reading the rest of the code, I assumed that : _alpm_* == private alpm_* == public (so with SYMEXPORT) Is this a real rule ? If so, should all functions in alpm_list.c be symexported, or should the ones without SYMEXPORT be renamed to _alpm_* ?
