Submitted by IncludeHelp, on November 13, 2021

In the Go programming language, to get the parent process identification using syscall – we use the Getppid() function of the syscall package. The Getppid() function returns the process ID of the parent of the calling process.

Syntax:

func Getpid() (pid int)

Consider the below example demonstrating how to get the parent process identification using syscall in Golang?

package main

import (
	"fmt"
	"syscall"
)

func main() {
	// Using the Getpid(),
	// Getting the parent process ID
	pid := syscall.Getgid()

	// Printing the parent process ID
	fmt.Println("parent process ID:", pid)
}

Output

parent process ID: 14022
