title: Tutorial or example for zookeeper C binding
body: <p>I am trying to create an application that uses the zookeeper C/C++ api. I would like to get a few examples on how they are used. I perused through the <a href="http://zookeeper.apache.org/doc/r3.1.2/zookeeperProgrammers.html#C+Binding" rel="noreferrer">official documentation</a>, but a lot of details are missing, many sections are listed as TODOs. I looked through the code examples, but there are hardly any comments, which makes it difficult to understand what's going on. Could anybody help with some documentation specifically for creating C bindings?</p>
  
  <p>FYI: I checked the usual channels, google, official documentation etc.</p>
