Invalid signal: SIGINT process.kill("SIGINT")

I follow the code at the bottom of the document page to execute an invalid type error

import { mergeReadableStreams } from "https://deno.land/[email protected]/streams/merge_readable_streams.ts";

// create the file to attach the process to
const file = await Deno.open("./hello.txt", {
  read: true,
  write: true,
  create: true,
});

// start the process
const process = Deno.run({
  cmd: ["yes"],
  stdout: "piped",
  stderr: "piped",
});

// example of combining stdout and stderr while sending to a file
const joined = mergeReadableStreams(
  process.stdout.readable,
  process.stderr.readable,
);

// returns a promise that resolves when the process is killed/closed
joined.pipeTo(file.writable).then(() => console.log("pipe join done"));

// manually stop process "yes" will never end on its own
setTimeout(() => {
  process.kill("SIGINT"); //Change to SIGTERM, no error
}, 100);

error: Uncaught TypeError: Invalid signal: SIGINT
process.kill("SIGINT"); //SIGTERM

The problem is that SIGINT isnt supported on windows currently; the manual should reflect that

[dong-lufei]

This code works fine on windows：

console.log("Press Ctrl-C to trigger a SIGINT signal");

Deno.addSignalListener("SIGINT", () => {
  console.log("interrupted!");
  Deno.exit();
});

// Add a timeout to prevent process exiting immediately.
setTimeout(() => {}, 5000);

to further specify: killing a subprocess is currently not supported on windows.
