<p class=MsoNormal>Hi Yin,<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>the problem with your approach is that you would not simply
be able to do the API equivalent of “set args” and then return.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>If you are going down the SBLaunchInfo route, you will also
need to launch through the API (what you do is make an SBLaunchInfo and then
pass it to SBTarget::Launch, and get an SBProcess back)<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Once you are in the business of launching through the API,
you might also want to start listening to process events for your launched
inferior<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>It seems like, pending a fix for the settings set bugzilla
issue (thanks for filing, btw), going the API way might be your best bet, as I
think others have pointed you at<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>A good example of how to do that is in
examples/python/process_events.py, or the whole lldb-perf project if you’re
more of a C++ developer<o:p></o:p></p>

<p class=MsoNormal>Since our settings set command is meant to set any kind of
setting, it makes sense that we ask for an argument. If we were to allow
setting set <foo> <end of command>, we would probably need a way to
know which is the “default value” for any specific setting. Feel free to file
an ER bugzilla for that too<o:p></o:p></p>
