Automatic termination with return code from a native_posix main function

[ivanwagner]

Is your enhancement proposal related to a problem? Please describe.
A clear and concise description of what the problem is.

I have a running application compiled for the native_posix target and I need this application to terminate automatically. In fact the what I see is that the Zephyr OS just hangs where after all the output I see on the console.

Is this somehow possible? Even just a "return;" statement within my main doesn't actually return.

I need a return code from this application so that another application can read it and take further actions.

Is this somehow possible? If not, can it be added somehow? I can contribute but don't know how the native_posix target actually works.

Thank you,

ivan

I've seen that if -stop_at=0 is provided to the native_posix binary image then the process returns as soon as the user main function terminates.

What about the return code? Is there any control over that?

I found a solution by using native_get_test_cmd_line_args to parse args given with -testargs and posix_exit to actually give my own return code and exit the application.
