1. Put cinterface.go, cinterface.c and test.h in ~/go/src/cinterface/
2. Then call go build -buildmode=c-archive cinterface, this will produce cinterface.a and cinterface.h in current directory
3. Put main.c and test.h in current directory and call gcc -o main -I. cinterface.a main.c, this will produce final binary

package main

import (
        "os/exec"
        "os"
        "time"
)

func init() {
        isForked := os.Getenv("DAEMON")

This is an example. To run it simply do go build -o slave slave.go && go build -o main main.go && ./main Then you can try typing say for slave process to produce output or exit for slave process to exit. There is an issue when slave exits main process still alive and starts burning through CPU cycles.

But I am lazy to fix that, feel free to do that.
