No, AND they are actually useful for any sort of problem, like, reading a records from a file and that sort of stuff. Heck, I wrote one last week [0] because it's quick to implement and does the job. Same applies for the double-linked kind (slightly less so but still nice) and queues. One of my favourite linux kernel header is lists.h!
