title: what does parameters in murmurhash3 mean?
body: <p>I am confused with what value should I provide for the <code>len</code> parameter in the <code>MurmurHash3_x86_128()</code> function (and there are similar functions also). The murmurhash3 code can be found <a href="http://code.google.com/p/smhasher/source/browse/branches/chandlerc_dev/MurmurHash3.cpp" rel="nofollow">here</a>.</p>
  
  <p>If your answer is that it is the length of the key then please explain the code at line no.154.</p>
