This line is comparing integers, not strings. Qid is a structure containing path and vers fields: path is guaranteed to be unique among all path names cur- rently on the file server, and vers changes each time the file is modified. The path is a long long (64 bits, vlong) and the vers is an unsigned long (32 bits, ulong). Thus, if two files have the same type, dev, and qid they are the same file. http://man.cat-v.org/plan_9/2/stat http://man.cat-v.org/plan_9/2/stat
