methods use va_list in a manner that is directly related to the public API. This makes it much easier to write dynamic nsswitch backends for getgrent(3). Per my proposal on tech-userlevel. Implement getgrgid_r() and getgrnam_r() APIs per the POSIX 1003.1, 2004 Ed. These aren't fully reentrant or threadsafe yet, because the compat stuff currently uses non-reentrant data sources (getnetgrent(3), getgrent(3)), and there is probably some locking to be improved in the backends. This will be fixed in the near future. We also need to add _SC_GETGR_R_SIZE_MAX to sysconf(3).
