[Cbc] How to set the DIRECTORY param

[ycollet at freesurf.fr]

Hello,

I was looking at the CbcSolver class and found a lot of parameters.

First question:
I was not able to see how to change the parameter DIRECTORY via the  
CbcSolver class ?

Another question:
If I use CbcMain1, how do I format the options sent to CbcMain1 via  
the argv list of strings ?

Your sincerely,

YC
