New submission from anatoly techtonik : ctypes documentation lacks an example, how to pass a raw data block from Python to a C function. For example, how to pass this chunk: data = open('somefile', 'rb').read() to this function: int checkBuffer(LPSTR lpData, DWORD dwBufferLength); ? ---------- assignee: docs@python components: Documentation, ctypes messages: 139675 nosy: docs@python, techtonik priority: normal severity: normal status: open title: ctypes: need example how to pass raw data from Python versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker http://bugs.python.org/issue12476 _______________________________________
