I need a binary tree similar to a std::map or a std::set, but unfortunately, the application must be in C. I looked at man tsearch, but it appears to lack these capabilities that I need: o general functionality of an iterator o ability to scan a range of the key, where no actual key values are known, e.g., a tree containing the keys 3 5 6 9 will return two values given the range [4...8]. Suggestions for another e-mail list or newgroup on which to ask this question would also be appreciated. Thanks for your help. Mike. -- Michael D.
