Bindings for for OpenBSD's [pledge(2)](http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/pledge.2?query=pledge)

# What?

`pledge(2)` allows a process to ratchet down the privileges it requires to run, if it attempts to access

a privilege it has pledged to not use, it will be killed by the kernel.

# Example Usage

Install via npm:

```

npm install --save node-pledge

```

```JavaScript

var http = require('http');

var pledge = require('node-pledge');

pledge.init("stdio rpath wpath prot_exec");

console.log("stuff");

// try to do something with http (will cause the kernel to kill node)

http.get("http://www.google.com/", function(res) {

  console.log(res);

}).on('error', function(e) {

  console.log(e);

});

```

Output:

```

node stuff.js

stuff

Abort trap (core dumped) 

```

Line from `dmesg(8)`:

```

node(24353): sysctl 6: 4 17 0 0 3 0

node(24353): syscall 202 ""

```
