Make System Calls

System Calls

Make System Calls in Dart. You can rewrite almost any C program now in Dart!

Currently this library supports Linux and Mac OSX. In the future, there will be partial support for Windows.

Examples

This is just a few examples of what is possible.

fork

import "package:syscall/syscall.dart";

void main() {
  print("Prepare to be forked!");
  var pid = fork();
  
  if (pid == 0) {
    print("I am the original process.");
    wait();
  } else {
    print("I am the child process.");
  }
}

chroot

import "dart:io";

import "package:syscall/syscall.dart";

void main(List<String> args) {
  if (args.length == 0) {
    print("usage: chroot <path> [command]");
    exit(1);
  }

  chroot(args[0]);

  var cmd = args.skip(1).join(" ");

  if (cmd.isEmpty) {
    cmd = "bash";
  }

  system(cmd);
}

setuid

import "package:syscall/syscall.dart";

void main() {
  print("Attempting to Gain Superuser.");
  try {
    setUserId(0);
    print("Success.");
  } catch (e) {
    print(e);
  }
}
