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

[Xavier]

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_* ?
