(Note: this is a compiled distribution of ctypes, compiled for cygwin
to allow using the cygwin conversions directly from interpreterInfo. The tests
have been removed to reduce the added size. It is only used by PyDev on cygwin).
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, MacOS X, Linux, Solaris, FreeBSD. It may
also run on other systems, provided that libffi supports this
platform.
On Windows, ctypes contains (the beginning of) a COM framework
mainly targetted to use and implement custom COM interfaces.
News
ctypes now uses the same code base and libffi on all platforms.
For easier installation, the libffi sources are now included in
the source distribution - no need to find, build, and install a
compatible libffi version.
Requirements
ctypes 0.9 requires Python 2.3 or higher, since it makes intensive
use of the new type system.
ctypes uses libffi, which is copyright Red Hat, Inc. Complete
license see below.
Installation
Windows
On Windows, it is the easiest to download the executable
installer for your Python version and execute this.
Installation from source
Separate source distributions are available for windows and
non-windows systems. Please use the .zip file for Windows (it
contains the ctypes.com framework), and use the .tar.gz file
for non-Windows systems (it contains the complete
cross-platform libffi sources).
To install ctypes from source, unpack the distribution, enter
the ctypes-0.9.x source directory, and enter
python setup.py build
This will build the Python extension modules. A C compiler is
required. On OS X, the segment attribute live_support must be
defined. If your compiler doesn't know about it, upgrade or
set the environment variable CCASFLAGS="-Dno_live_support".
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]
For Windows CE, a project file is provided in
wince\_ctypes.vcw. MS embedded Visual C 4.0 is required to
build the extension modules.
