This commit moves the C++ samples under `samples/subsys/cpp` to `samples/cpp` because the C++ language and standard library support is not a "subsystem" (aka. API) in conventional sense and the samples demonstrating them should belong directly under the top samples directory as does POSIX support.

Overview
|
|
********
|
|
The sample project illustrates usage of pure virtual class, member
|
|
functions with different types of arguments, global objects constructor
|
|
invocation.
|
|
|
|
A simple application demonstrates basic sanity of the kernel. The main thread
|
|
and a cooperative thread take turns printing a greeting message to the console,
|
|
and use timers and semaphores to control the rate at which messages are
|
|
generated. This demonstrates that kernel scheduling, communication, and
|
|
timing are operating correctly.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
This kernel project outputs to the console. It can be built and executed
|
|
on QEMU as follows:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/cpp_synchronization
|
|
:host-os: unix
|
|
:board: qemu_x86
|
