How to interact with the system's process table and process-related information using syscall in Golang?

In Go, you can use the os package to interact with the system's process table and process-related information. Here are some examples of how to use syscall in Go to get process-related information:

Get the current process ID (PID):

package main

import (
	"fmt"
	"os"
)

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

Get the parent process ID (PPID):

package main

import (
	"fmt"
	"golang.org/x/sys/unix"
)

func main() {
	ppid, _ := unix.Getppid()
	fmt.Println("Parent Process ID:", ppid)
}

Get the list of processes in the system's process table:

package main

import (
	"fmt"
	"io/ioutil"
	"strconv"
)

func main() {
	files, _ := ioutil.ReadDir("/proc")
	for _, file := range files {
		if file.IsDir() {
			name := file.Name()
			pid, _ := strconv.Atoi(name)
			fmt.Printf("Process: %d\n", pid)
		}
	}
}

Get process status:

package main

import (
	"fmt"
	"io/ioutil"
)

func main() {
	pid := 1234 // Replace with the desired PID

	status, _ := ioutil.ReadFile(fmt.Sprintf("/proc/%d/status", pid))
	fmt.Println(string(status))
}

These examples provide a starting point for interacting with the system's process table and process-related information using syscall in Go. However, keep in mind that the precise way to interact with process-related information can vary depending on the specific operating system and Go version being used.
