[Ipopt] Ipopt report issue

[Anders Gustafsson]

Dear Stefan,

many thanks for referring to the updated C interface. I am the main
developer of csipopt, the Ipopt .NET interface
(http://code.google.com/p/csipopt) that I assume you are using,
Sebastian. I was not aware of these additions to the C interface, but
I will definitely implement a C# wrapper for the new callback as soon
as possible.

Sebastian, if you are interested in further discussing the design of
the C# wrapper (or have other ideas on how it should be done), I have
started a discussion forum for csipopt at
http://groups.google.com/group/csipopt. Please feel free to join and
post your ideas in this forum.

Regards,
Anders Gustafsson
