From: Doug Gwyn <gwyn@Brl> Date: 25 Oct 82 10:12:06-EDT (Mon) If someone is about to implement a package for balanced tree ops, please try to keep it as compatible as possible with tsearch(3C): char *tsearch( char *key, char **rootp, int (*compar)() ) char *tdelete( char *key, char **rootp, int (*compar)() ) void twalk( char *root, int (*funct)() ) We already have enough trouble with incompatibilities with Bell UNIX that we don't need another. (Implementors: if you can't figure out these interfaces, drop a note.)
