Is there a way to go about killing a process after spawning it on a SIGINT?

I can't do this for e.g. because kill is not @nogc.

Well, this works:

import std;
import core.stdc.signal;

extern(C) int kill(int pid, int sig) nothrow @nogc @system;

int currentSpawnedPid;

extern(C) void killCurrentPidHandler(int sig) nothrow @nogc @system {

  if (currentSpawnedPid > 1)
    kill(currentSpawnedPid, sig);
}

int main() {

auto pid = spawnProcess(["sleep", "50s"], stdin, stdout, stderr);

  currentSpawnedPid = pid.processID;
  signal(SIGINT, &killCurrentPidHandler);
  return wait(pid);
}

Thanks, looks like I'll have to go that route.
