Get a supported operating system signal for terminating a local process.
Value
An integer of length 1: tools::SIGTERM if your platform
supports SIGTERM. If not, then crew_crew_terminate_signal()() checks
SIGQUIT, then SIGINT, then SIGKILL, and then returns the first
signal it finds that your operating system can use.
