Is your enhancement proposal related to a problem? Please describe.
The socketpair(2) system call was recently added as experimental.
It would be good to have an example for using it.
Describe the solution you'd like
A simple sample application that demonstrates several threads communicating over several socket pairs, preferably using the BSD Sockets API and standard POSIX system calls such as read(2) and write(2).
I have a sample application that I could make a PR for.
Currently works fine compiling natively (i.e. using Makefile.posix) and building for Zephyr target native_posix_64. However, I run into some issues when moving to qemu_cortex_m3 likely to some C++ things that are not yet supported in Zephyr. Might require some slight modification.
Describe alternatives you've considered
Not using C++.
