Signalling Processes

Function: signal-process process-object signal-number &optional whole-group

If the process object process-object is being used to run an asynchronous subprocess send the signal numbered signal-number to it.

When the optional argument whole-group is non-nil the signal is also sent to all processes in the process group of the subprocess.

The following functions use the signal-process function to send some common signals to processes.

Function: interrupt-process process-object &optional whole-group

Sends the SIGINT signal to process-object.

(interrupt-process process-object whole-group)
==
(signal-process process-object SIGINT whole-group)

Function: kill-process process-object &optional whole-group

Sends the SIGKILL signal to the process-object.

(kill-process process-object whole-group)
==
(signal-process process-object SIGKILL whole-group)

Note that the functions stop-process and continue-process also send signals to the subprocess.
