Overview ctypes is a ffi (Foreign Function Interface) package for Python. It allows to call functions exposed from dlls/shared libraries and has extensive facilities to create, access and manipulate simpole and complicated C data types transparently from Python - in other words: wrap libraries in pure Python. ctypes runs on Windows, Windows CE, MacOS X, Linux, Solaris, FreeBSD, OpenBSD. It may also run on other systems, provided that libffi supports this platform. ctypes includes libffi, which is copyright Red Hat, Inc. Complete license see below. Requirements ctypes requires Python 2.3 or higher, since it makes intensive use of the new type system. In Python 2.5, the ctypes package is already included. Installation Windows On Windows, it is the easiest to download the executable installer for your Python version and run it. Installation from source To install ctypes from source, unpack the distribution, enter the ctypes-x.y.z source directory, and enter python setup.py build This will build the Python extension modules. A C compiler is required. To run the supplied tests, enter python setup.py test To install ctypes, enter python setup.py install --help to see the avaibable options, and finally python setup.py install [options] Windows CE Required software to build the _ctypes.pyd extension module for Windows CE (all these are free downloads): - Embedded Visual C 4.0 with service pack 2 (3?, 4?) - Pocket PC 2003 SDK - The Python 2.3 or 2.4 windows CE development files: include files, header files. Open the wince\_ctypes.vcw project file with embedded visual C 4.0. Select "POCKET PC 2003", "Win32 (WCE ARMV4) Release", and "POCKET PC 2003 Device" in the comboboxes. From the menu, select Tools->Options->Directories, and add these directories: Include files: add c:\Python-2.4.3-wince-dev\INCLUDE Library files: add c:\Python-2.4.3-wince-dev\LIB Right click '_ctypes files' in the FileView, select 'Settings', then the 'Debug' tab. Enter '\Program Files\Python24' in the 'Download directory' box. Do the same for the '_ctypes_test' project. Now you can connect your pocket PC, build the projects in visual C, and both _ctypes.pyd and _ctypes_test.pyd should be downloaded automatically to your device. ctypes license Copyright (c) 2000, 2001, 2002, 2003, 2004, 2005, 2006 Thomas Heller Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
