The idiomatic way to sort something in C is to use the
qsort()function. For this to work, it’s best if you can arrange to have all the file names collected into an array of pointers, and then you sort the array.This is not too hard, but it does require either a bit of dynamic-array management, or that you introduce static limits on things (maximum length of filenames, maximum number of files).
