Hello, I'd like to call PyOS_Readline or a particular readline hook function via ctypes. The problem is that the functions accepts stdin and stdout file pointers as first two arguments. These are usually pointers to the standard stdin and stdout files. But how to get the file pointers in Python 3? In Python 2, one could do PyFile_AsFile(py_object(sys.stdin)). I'm asking here since it is quite specific Python implementation related question. Actually, no one answered me on python-list ( https://mail.python.org/pipermail/python-list/2015-July/694633.html). Regards, Adam Bartoš
