New submission from Daniel Standage: The ctypes documentation describes the '._as_parameter_' attribute, which simplifies using Python objects to encapsulate C objects. If a ctypes object with the '._as_parameter_' attribute defined is passed as a parameter to a C function, the value of '._as_parameter_' is supplied to the C function instead of a pointer to the Python project.
At least that's how it's advertised to work. And it does indeed work as advertised on Linux, but on Mac OS X the mechanism doesn't appear to work correctly. I have created a small dummy example demonstrating this at https://github.com/standage/ctypes-demo. ---------- components: ctypes hgrepos: 281 messages: 231692 nosy: Daniel.Standage priority: normal severity: normal status: open title: Ctypes inconsistent between Linux and OS X type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22945> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
