An Ipopt::IpoptApplication object has a function Statistics() which 
returns you a pointer to a Ipopt::SolveStatistics object. That should 
give you all required information.

With make doxydoc you can generate a source code documentation for 
Ipopt, which could be handy. (the online one does not seem to work 
currently)
