Using ctypes to call C code from Python (Python)

2016-05-09T18:00:44-07:00

Python recipe 580660 by Vasudev Ram (ctypes, ffi, python, time).

This recipe shows basic usage of the ctypes module to call C code from Python code.

Simple video with ctypes and Xvid (Tkinter,pygame,...) (Python)

2015-06-29T13:59:38-07:00

Python recipe 579073 by Jiri Justra (ctypes, video, xvid).

This is simple library for playing avi video clips. Videos must be SOUNDLESS (and maybe Xvid encoded wont hurt), to work it properly. I am using it to play intro. It suites good to this purpose, since it can play one clip at a time only.

Reimplementation of rmtree supporting Windows reparse points (Python)

2014-03-08T21:17:41-08:00

Python recipe 578849 by Charles Grunwald (ctypes, directories, files, remove, win32). Revision 3.

Ctypes-based implementation of shutil.rmtree that correctly handles Windows reparse point folders. (symbolic links, junctions, etc)

Windows directory walk using ctypes (Python)

2013-08-09T00:17:00-07:00

Python recipe 578629 by Shao-chuan Wang (ctypes, system).

Windows shell/explorer has a limit size of full path, but both NTFS and ReFS can support full path longer than the limit; this is making os.walk on Windows bad if files are in deeply nested folders, and therefore this recipe.

car.py (Ctypes ARchiver in PYthon [libarchive ffi wrapper]) (Python)

2013-05-28T04:02:15-07:00

Python recipe 578531 by Mike 'Fuzzy' Partin (bzip2, cpio, ctypes, ffi, gzip, lzma, pax, python, tar). Revision 3.

CTypes libarchive wrapper, handles extraction only with no arguments.

DDE Client (Python)

2011-04-14T16:33:19-07:00

Python recipe 577654 by David Naylor (ctypes, dde, win32).

A DDE Client using ctypes for Windows. Unlike the pywin32 implementation this code supports advice requests.

How to Mutate a Float (Python)

2012-05-14T16:49:13-07:00

Python recipe 578132 by Stephen Chappell (ctypes, experiment, float, structure).

This is just an experiment to test my mental understanding of Python. It should not be used in any code as is violates the design principle that floats are to be immutable. The code also abuses ctypes and an understanding of how floats are currently arranged in memory. set_float is not guaranteed to work properly on any system, and may fail to work in the future if the data's arrangement changes.

POSIX Semaphore (FreeBSD) (Python)

2011-04-14T17:54:16-07:00

Python recipe 577655 by David Naylor (ctypes, freebsd, semaphores, signal, threads).

POSIX Semaphore bindings for FreeBSD.

Calling (C-level) finalizers without del (Python)

2011-07-02T18:42:08-07:00

Python recipe 577242 by Benjamin Peterson (ctypes, finalization, weakref). Revision 3.

This recipe is meant for Python classes wrapping ctypes bindings where a C-level finalizer must be invoked when the wrapper is destroyed. It uses weakref callbacks to avoid problems with __del__.

Altering immutable string object. (Python)

2010-01-11T06:11:05-08:00

Python recipe 577000 by Pepe Aracil (ctypes, immutable). Revision 3.

"Useless" alteration of immutable string object in 100% pure python. :)

Thinkpad Turtle (Python)

2010-03-26T20:04:05-07:00

Python recipe 576985 by Michael Grünewald (ctypes, thinkpad, win32, windows). Revision 4.

A small program utilizing the ctypes and turtle modules. You can drive the little turtle by turning your Thinkpad (which must have APS).

Requirements:

You need a newer Thinkpad (T41, T42, T43, T6x, R5x, R6x or any newer) and need to have the Active Protection System drivers (now called Lenovo Airbag Protection) installed.

Detect when system is idle (Python)

2009-05-31T01:18:03-07:00

Python recipe 576786 by Gabriel Genellina (ctypes, idle, idle_time, time, user_input, windows).

Detect when system is idle, globally. That is, the user is not moving the mouse nor typing anything, in any application (not just our program).

Shutdown your PC by using ctypes (Win32 Platform) (Python)

2009-08-03T10:05:38-07:00

Python recipe 576865 by Shao-chuan Wang (ctypes, reboot, shutdown, system_programming, win32).

It is true that by using win32 extension python modules, such as win32api, win32con, and win32security, we can easily shutdown the computer with a few steps. However, sometimes your python's runtime environment does not provide win32com module (because it is not a build-in module), we may have to shutdown the pc on our own.

By using ctypes, we are still able to shutdown or reboot the PC easily.

C function decorator (Python)

2009-04-29T23:55:03-07:00

Python recipe 576731 by geremy condra (cpp, ctypes, decorator, function). Revision 6.

This recipe provides an easy-to-use, decorator-based solution to the problem of using functions from other languages, especially C, in Python. It takes advantage of Python's new annotations to provide simple type checking and automatic conversion. If you like it, you may also want to check out my C structure decorator

ctype Enumeration class (Python)

2008-08-10T16:45:46-07:00

Python recipe 576415 by Devan L Devan L (ctypes).

An example Enumeration class and metaclass to declare an enumeration in ctypes.

Control CPU Usage by using ctypes (Win32 Platform) (Python)

2009-01-26T09:32:34-08:00

Python recipe 576634 by Shao-chuan Wang (cpu_usage, ctypes, system_programming, win32). Revision 3.

This program will make your cpu work at a given cpu usage. It should be also able to work on machines with multi-processors. The program has been tested on Windows xp sp2 with python of version 2.5.4.

The implementation is based on the fact that it will adjust the ratio of being busy over being idle in the main process to approach the target cpu usage rate.

Get CPU Usage by using ctypes (Win32 Platform) (Python)

2009-01-26T06:43:38-08:00

Python recipe 576631 by Shao-chuan Wang (cpu_usage, ctypes, system_programming, win32). Revision 2.

The following code has been tested at Windows XP sp2 with Python of version 2.5.4.

Low level inotify wrapper (Python)

2013-08-12T14:39:57-07:00

Python recipe 576375 by Louis RIVIERE (ctypes, inotify, linux, system). Revision 10.

This module is meant to be as simple and straightforward as it gets.

Calling Windows API using ctypes and win32con (Python)

2008-07-25T20:01:50-07:00

Python recipe 208699 by Gary Eakins (ctypes, windows_api). Revision 4.

It is easy to call Windows API dlls using the ctypes module with win32con defining the constant values for message identifiers and parameter flags. The demo code shows a simple but complete application that registers a window class and a Python WndProc callback function, creates the window and pumps messages.
