</div>Looks good, except for one point. In your callback, you have this:<br>
<br>
params* input = ...<br>
<br>
That is a very poor choice of name for this variable. The example<br>
would be much more clear if you called the variable params, and then<br>
used a more descriptive name for the struct.<br>
