You should be safe if you mark the struct only allocable by the function
providing the array of infos, only accessible by pointer, and you append
fields in the end.

If you feel somebody would do something stupid like making a

struct mine{
	libvlc_media_track_info_t info;
	int mine;
}

(or it is used)

Then would be better come up with an additional info struct, marked
accordingly and mark the old one for deprecation.
