title: What is CFErrorDomainLaunchd error 2?
body: <p>I can't find CFErrorDomainLaunchd in any of the headers.  I used the
  find command to grep every header file in the 10.11 SDK.</p>
  
  <p>I also tried google:</p>
  
  <pre><code>site:opensource.apple.com CFErrorDomainLaunchd
  </code></pre>
  
  <p>SMJobBless passes the error back when I try to install my helper app
  and its launchd plist.</p>
  
  <p>I'm quite puzzled because that installation was working just fine
  yesterday.  I hereby resolve to check my code in far more frequently
  than I presently do.</p>
  
  <pre><code>Boolean             success;
  CFErrorRef          error;
  
  success = SMJobBless(
      kSMDomainSystemLaunchd,
      CFSTR("com.frescologic.FL2000.Uninstaller.UninstallerHelper"),
      self-&gt;_authRef,
      &amp;error );     &lt;-- This is CFErrorDomainLaunchd error 2
  </code></pre>
  
  <p>I am eternally in your debt.</p>
  
  <p>I'm developing - or trying to develop - an uninstaller for a driver.  It will also uninstall a user space program as well as the LaunchAgent plist that OS X uses to start or stop that user space program.</p>
