Golang : Get own process identifier

There are times when developer needs to know the own process identifier(PID) of the executing program during runtime. This is to facilitate task such as scheduling graceful shutdown of the process or for other reasons.

This short code example utilized the os.Getpid() function to retrieve own process identifier.

 package main

 import (
 "fmt"
 "os"
 "strconv"
 )

 func main() {
 pid := os.Getpid()
 fmt.Println("Own process identifier: ", strconv.Itoa(pid))
 }
