Re: ctypes char array question

There needs to be a method of accessing that information.  I can't force
developers to modify their embedded source code or hack in a work around on
the python side every time I generate ctypes from the embedded C code.
That's not a good long term solution.

Any thoughts on if/when this could be added?  Is there no way to access the
underlying raw data?

All the data continuously generated in your IT infrastructure 
contains a definitive record of customers, application performance, 
security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.
