I'm writing some command line tooling stuff, and one of the command spins up a docker compose file (which in short, spins up some services and aggregates the output of each service to stdout).

When a user presses ctrl+c, i would like to pass on the ctrl+c to the spawned process and wait till it handles ctrl+c and then let go of the current process.

So far I have this:

int spawnedPid;

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

extern(C) void interruptHandler(int sig) nothrow @nogc @system {
    kill(spawnedPid, sig);
}

int spawnProcessAndWait(string[] cmd) {
    auto pid = spawnProcess(cmd, stdin, stdout, stderr);
    spawnedPid = pid.processID;
    signal(SIGINT, &interruptHandler);
    int result = wait(pid);
    return wait(pid);
}

It doesn't work. I think the call to kill doesn't wait? Is there a way to make it wait?

I can't call kill(Pid) or wait(Pid) inside the interrupt handler because those are not @nogc [0].
