Would this be a start?

IIUC, you return to the same problem. You can't pass that z_t thing to zconverter() through CFFI. What you have to do is, for each foreign function that wants a complex number as parameter, write a C wrapper that will take two doubles (in addition to whatever other arguments the functions wants) and call the appropriate function with a newly created complex number. Similar wrapping would be necessary for functions that return complex numbers.

HTH.
