C Minimal Perfect Hashing Library (CMPH) 是一个可移植的基于 LGPL 协议发布的 C 语言的哈希函数库。该库封装了最新而且最高效的算法，易用，稳定、快速。

示例代码：

  #include <cmph.h>    #include <string.h>    // Create minimal perfect hash function from in-memory vector    int main(int argc, char **argv)    {             // Creating a filled vector        unsigned int i = 0;        const char *vector[] = {"aaaaaaaaaa", "bbbbbbbbbb", "cccccccccc", "dddddddddd", "eeeeeeeeee",             "ffffffffff", "gggggggggg", "hhhhhhhhhh", "iiiiiiiiii", "jjjjjjjjjj"};        unsigned int nkeys = 10;        FILE* mphf_fd = fopen("temp.mph", "w");        // Source of keys        cmph_io_adapter_t *source = cmph_io_vector_adapter((char **)vector, nkeys);            //Create minimal perfect hash function using the brz algorithm.        cmph_config_t *config = cmph_config_new(source);        cmph_config_set_algo(config, CMPH_BRZ);        cmph_config_set_mphf_fd(config, mphf_fd);        cmph_t *hash = cmph_new(config);        cmph_config_destroy(config);        cmph_dump(hash, mphf_fd);         cmph_destroy(hash);         fclose(mphf_fd);            //Find key        mphf_fd = fopen("temp.mph", "r");        hash = cmph_load(mphf_fd);        while (i < nkeys) {            const char *key = vector[i];            unsigned int id = cmph_search(hash, key, (cmph_uint32)strlen(key));            fprintf(stderr, "key:%s -- hash:%u\n", key, id);            i++;        }            //Destroy hash        cmph_destroy(hash);        cmph_io_vector_adapter_destroy(source);           fclose(mphf_fd);        return 0;    }
