title: What does the first "c" stand for in "calloc"?
body: <p>A student asked the question and I didn't know for sure.  </p>
  
  <p>Guesses include: "counted", "clearing", "chunked", "complete", ...</p>
  
  <p>The standard library documentation doesn't say what it stands for and there aren't similarly named functions that would indicate a pattern.  Does anyone know the actual etymology and perhaps have an authoritative reference to back it up?</p>
