Send signal to a process

Description

Send a signal to the process. Not implemented on Windows. See signals() for the list of signals on the current platform.

Usage

ps_send_signal(p, sig)

Arguments

Details

It checks if the process is still running, before sending the signal, to avoid signalling the wrong process, because of pid reuse.

Examples

px <- processx::process$new("sleep", "10")
p <- ps_handle(px$get_pid())
p
ps_send_signal(p, signals()$SIGINT)
p
ps_is_running(p)
px$get_exit_status()
