[Confuse-devel] Deleting a section...

[Sergey Katsev]

I'm trying to programmatically delete a section.  Here's some background:

Martin replied and said this isn't currently supported so I'm looking for a way 
to implement it.

What I'm trying right now is using cfg_free() on opt->values[i]->section, and 
then decrement opt->nvalues.  

However, it looks like although it "works", it corrupts memory so the next time 
I try to use the in-memory parsed data, I get core dumps.  Is there something 
else that I'm not cleaning up that I should be?

Thanks in advance.
