I'll agree the verb is not perfectly clear, but the driver author should make sure the correct action is taken regardless of the function name.</p>
<p dir="ltr">It's possible we should just rename the function to something like "unget_cert", which sounds a bit nonsensical but is possibly still clearer. I remember at the time I wrote this being frustrated with trying to name the function and wanting to just move on. T_T</p>
