ps_send_signal: Send signal to a process

In ps: List, Query, Manipulate System Processes

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 = ps_handle(), sig)

Arguments

p	Process handle.
sig	Signal number, see signals().

Details

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