93 .\"O .BR fts_children ()
94 .\"O returns a pointer to a linked list of structures, each of which describes
95 .\"O one of the files contained in a directory in the hierarchy.
96 .\"O In general, directories are visited two distinguishable times; in preorder
97 .\"O (before any of their descendants are visited) and in postorder (after all
98 .\"O of their descendants have been visited).
99 .\"O Files are visited once.
100 .\"O It is possible to walk the hierarchy "logically" (ignoring symbolic links)
101 .\"O or physically (visiting symbolic links), order the walk of the hierarchy or
102 .\"O prune and/or revisit portions of the hierarchy.
