[Coin-discuss] accessing the Clp solver from Cbc/Clp

[John J Forrest]

You need to use dynamic_cast to get an OsiClpSolverInterface pointer from
an OsiSolverInterface pointer.  See an example at line 155 of repeat.cpp.
It will be a valid pointer if it was an OsiClpSolverInterface pointer NULL
otherwise.

So you can also use it to see what solver you have.  You can also use
getStrParam(OsiSolverName,std::string&)

This returns an OsiSolverInterface *, which doesn't have a getModelPtr(),
or
is there someway of getting from this to OsiClpSolverInterface? [this may
reflect my lack of knowledge on C++, rather than anything else]
