21 | To use rbtrees you'll have to implement your own insert and search cores. | ||
22 | This will avoid us to use callbacks and to drop drammatically performances. | ||
23 | I know it's not the cleaner way, but in C (not in C++) to get | ||
24 | performances and genericity... | ||
25 | |||
26 | Some example of insert and search follows here. The search is a plain | ||
27 | normal search over an ordered tree. The insert instead must be implemented | ||
28 | int two steps: as first thing the code must insert the element in | ||
29 | order as a red leaf in the tree, then the support library function | ||
30 | rb_insert_color() must be called. Such function will do the | ||
31 | not trivial work to rebalance the rbtree if necessary. | ||
