How to get the current working directory of a process using syscall in Golang?

To get the current working directory of a process using syscalls in Go, you can use the syscall.Getwd() function. Here's an example:

package main

import (
    "fmt"
    "os"
    "syscall"
)

func main() {
    pid := os.Getpid()
    cwd, err := syscall.Getwd()
    if err != nil {
        fmt.Println("Error getting current working directory:", err)
        return
    }
    fmt.Printf("Current working directory of process %d: %s\n", pid, cwd)
}

In this example, we first retrieve the process ID (PID) using os.Getpid(). Then, we use syscall.Getwd() to get the current working directory. If there is an error, we handle it accordingly. Finally, we print the current working directory along with the process ID.
