/** cmph_uint32 cmph_search_fingerprint(cmph_t *mphf, const char *key, cmph_uint32 keylen, cmph_uint32 * fingerprint);

* \param mphf pointer to the resulting function
* \param key is the key to be hashed

* Computes the mphf value and a fingerprint of 12 bytes. The figerprint pointer should be
* a prealocated area to fit three 4-byte integers. You don't need to use all the 12 bytes
* as fingerprint. According to the application, just few bits can be enough, once mphf does
* not allow collisions for the keys previously known.
