* Tom: the issue is unrelated to cffi, but both ctypes and cffi could proceed to support C complexes, now that libffi support has been added.
* Mark: the problem is that the text you quote from the C standard fixes the representation of a complex in memory, but doesn't say anything about directly passing a complex as argument or return value to a function call. Platforms use custom ways to do that. The text you quote says a complex is an array of two real numbers; but passing an array as argument to a function works by passing a pointer to the first element. Typically, this is not how complexes are passed: instead, some pointerless form of "passing two real numbers" is used. |
