Calling the function system("<command>") or systemlist("<command>") retrieves the stdout output from a shell call to <command>. How can I retrieve the exit status of that command?

For example, I would like to do something like this:

let output = system_call_with_exit_status("my_shell_command")
let stdout = output[0]
let exit_status = output[1]
if (exit_status != 0)
 echo output
endif

The intention is to print the output from my_shell_command only if the command gives a non-zero exit status.

Mentioned in the comments above, the v:shell_error variable gives the result of the last shell command. So the exit status can be tested as follows:

let output = system("my_shell_command")
if v:shell_error != 0
 echo output
endif
