69 * There are currently two cache structures where afpd caches directory information
70 * a) a DID/dirname cache in a hashtable
71 * b) a (red-black) tree with CNIDs as key
73 * a) is for searching by DID/dirname
74 * b) is for searching by CNID
76 * Through additional parent, child, previous and next pointers, b) is also used to
77 * represent the on-disk layout of the filesystem. parent and child point to parent
78 * and child directory respectively, linking 2 or more subdirectories in one
79 * directory with previous and next pointers.
81 * Usage examples, highlighting the main functions:
83 * a) is eg used in enumerate():
85 * dir = dirsearch_byname() // search in cache
86 * if (dir == NULL) // not found
87 * dir = adddir() // add to cache
90 * b) is eg used in afp_getfildirparams()
91 * dirlookup() // wrapper for cache and db search
92 * => dir = dirsearch() // search in cache
96 * cnid_resolve() // resolve with CNID database
97 * cname() // add to cache
