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.
