I have investigated the complex data types a bit and came to the conclusion that libffi (which ctypes is based upon) would have to be extended to support these complex types. I have not looked into the newer libffi sources to find out if this support already has been added, ctypes uses an older version of libffi. By experimenting I found out that on some systems (x86 linux and x86_64 linux) I could 'emulate' the complex type by defining a structure: class Complex(Structure): _fields_ = [("real", c_double), ("imag", c_double)] def _get(self): .... def _set(self, value): .... value = property(_get, _set) but I'm afraid this is not really portable to other platforms.
