How to get the process ID (PID) of the current process using syscall in Golang?

In Golang, you can use the syscall.Getpid() function to get the process ID (PID) of the current process.

Here is an example code snippet:

package main

import (
	"fmt"
	"syscall"
)

func main() {
	pid := syscall.Getpid()
	fmt.Println("Process ID:", pid)
}

In this code, syscall.Getpid() returns the process ID of the current process, and it is stored in the pid variable. The PID is then printed using fmt.Println().
