# OpenBSD Lua Library

Implements:

* pledge()

* arc4random()

* arc4random_uniform()

* unveil()

* auth_userokay()

Works and has been tested on Lua 5.1, 5.2, 5.3 and 5.4.

Note that pledge() pre 6.3 takes an optional set of paths as the second

argument.

```lua

-- OK

o.pledge('rpath stdio')

-- Error

o.pledge('rpath stdio', 'stdio')

```

## Build

Don't forget to set the `MODLUA_VERSION` variable to the Lua version you are

using.

```

$ mkdir build && cd build

$ cmake .. -DMODLUA_VERSION=5.4

$ make

$ make install

```

## Usage

```lua

#!/usr/bin/env lua51

o = require('openbsd')

ret, error_string = o.pledge('rpath stdio')

if ret == -1 then

   error(error_string)

end

```

Or:

```

#!/usr/bin/env lua54

o = require('openbsd')

for i = 1, 10 do

    print(o.arc4random_uniform(20))

end

```
