I love Judy, I have used it for years, its really the only dynamic array a C programmer needs .. ;) Well, okay Judy + list.h (from the linux kernel) == all you need!
It has singly-linked list, lists, simple queues, tail queues and circular queues.
If you're comfortable with Linux kernel style lists, then sys/queue.h will be familiar, and it's shipping in glibc and on BSD systems (where it was originally from).
