System V shared memory in Python?

Question

How can I make use of the shmat(), shmdt(), shmctl(), shmget() calls from Python? Are they hidden somewhere in the standard library?

Update0

I'm after System V bindings that can be found in the Ubuntu repositories, or Python standard libraries (now or in future releases).

If you don't want to use any non-standard Python libraries, perhaps you could wrap the functions you need yourself using ctypes?

This page offers a feature matrix to help you choose between the posix_ipc, sysv_ipc, and shm modules.

Does an ubuntu package exist for this? – Matt Joiner Jun 04 '10 at 10:19
@MattJoiner , There is no ubuntu package but can be installed via pip: # ```pip install sysv_ipc``` – Muhammad Yusuf Dec 12 '18 at 14:06
all 3 modules are absolutely trash, shm pypi page is empty, others 2 are not installable. And all 3 modules looks like abandoned. The best solution is to use ctypes – RandomB Oct 11 '19 at 09:09
I did not have trouble installing the sysv_ipc with Python 3.8. It appears to work. – Mark Lakata Jul 01 '21 at 00:37

The processing package also supports shared memory objects, and works on unix/mac/windows.
