The bad worst-case -behavior is a small price to pay, given that treaps are much simpler -to implement. - -API -=== - -The trp API generates a data structure and functions to handle a -large growing set of objects stored in a pool. - -The caller: - -. Specifies parameters for the generated functions with the - trp_gen(static, foo_, ...) macro. - -. Allocates a `struct trp_root` variable and sets it to {~0}. - -. Adds new nodes to the set using `foo_insert`. Any pointers - to existing nodes cannot be relied upon any more, so the caller - might retrieve them anew with `foo_pointer`. - -. Can find a specific item in the set using `foo_search`. - -. Can iterate over items in the set using `foo_first` and `foo_next`. - -.
