Just compile and link your program withmurmur3.c, and be sure to includemurmur3.hto get the function prototypes. There are three hash functions: void MurmurHash3_x86_32 (const void *key, int len, uint32_t seed, void *out); void MurmurHash3_x86_128(const void *key, int len, uint32...
In order to use murmur3 as a hamt hash function, we need to wrap it into a helper function: static uint32_t my_keyhash_string(const void *key, const size_t gen) { uint32_t hash = murmur3_32((uint8_t *)key, strlen((const char *)key), gen); return hash; } Here, the wra...
