I think your proposal is the best way. I had to do something similar many years ago with another scientist's FORTRAN code - in that case the code either asked for user input or simply called exit() - both of those being extremely bad behavior for a shared library. From my point of view your proposed change should be an improvement to the ngspice code (I hope it doesn't require as much refactoring as the fortran code I had to deal with).
