I'm writing some command line tooling stuff, and one of the command

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?
Hm.. are you sure that ctrl-c isn't also sending the signal to your
child process? I thought it did.
