While __attribute((sentinel)) (exposed by glib under G_GNUC_NULL_TERMINATED macro) is a gcc extension, it's supported by clang too. It's already being used throughout our code but some functions that take variadic arguments and expect NULL at the end were lacking such annotation. Fill them in. After this, there are still some functions left untouched because they expect a different sentinel than NULL. Unfortunately, glib does not provide macro for different sentinels. We may come up with our own, but let's save that for future work. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
