Search - binary trie c
Search list
Description: 写这个的出发点是吧之前做的trie能写到文件而且能很容易mmap到内存, 可以用于输入法 搜索引擎分词 词表的功能, 共享前缀存储, 支持最大２０亿节点.
简单一点可以当一个hash表使用, 查找的时间复杂度为 N* Log(256) N为字符长度, key可以为二进制的数据, value 必须为int类型, 不能为０, 因为mmtrie_get()/find() 没有结果的情况下为０,
如果需要set value为０的话自己+１, 出来的时候-１就好了.-Write the starting point is to do the trie before it can write files and can very easily mmap to memory, can be used to enter France search engine sub-word vocabulary, shared storage prefix supports up to two billion nodes. A simple thing can be when a Use hash table to find the time complexity is N* Log (256) N for the characters in length, key data for binary, value must be int type, can not be 0, because mmtrie_get ()/find () does not result in the situation is 0, if set value to 0 if its+1, out of time-1 enough.

Description: The cprops (C prototyping tools) library provides
a portable, thread-safe C API including linked list, binary heap, priority queue, hash table, hash list, trie, AVL, Red-Black, and splay tree implementations, a thread pool and thread management framework, a TCP and HTTP socket API, and a database abstraction layer with drivers for Postgres and MySQL. libcprops compiles and runs on Linux, BSD, Solaris, Mac OS X, and Win32.-The cprops (C prototyping tools) library provides a portable, thread-safe C API including linked list, binary heap, priority queue, hash table, hash list, trie, AVL, Red-Black, and splay tree implementations, a thread pool and thread management framework, a TCP and HTTP socket API, and a database abstraction layer with drivers for Postgres and MySQL. libcprops compiles and runs on Linux, BSD, Solaris, Mac OS X, and Win32.
