What's the difference between _Exit() and _exit()?
<p>In answer to <a href="http://stackoverflow.com/q/8804643/594137">this question</a>, some people have said to use <a href="http://stackoverflow.com/a/8804701/594137">_Exit()</a> and others have said to use <a href="http://stackoverflow.com/a/8804676/594137">_exit()</a>.  Could someone explain the difference (if any) between the two, and the origins of both?</p>
