ref-wchar
==========
### A ref "type" implementation of `wchar_t *` (a.k.a. wide string) backed by "node-iconv"
[](https://travis-ci.org/TooTallNate/ref-wchar)
[](https://ci.appveyor.com/project/TooTallNate/ref-wchar)
This module offers a ["wide
strings"](http://en.wikipedia.org/wiki/Wide_character#C.2FC.2B.2B) (`wchar_t *`)
implementation on top of Node.js Buffers using the ref "type" interface.
Installation
------------
Install with `npm`:
``` bash
$ npm install ref-wchar
```
Examples
--------
Say you have a C library that exports a `wchar_t` char and a `wchar_t *` wide
string:
``` c
#if defined(WIN32) || defined(_WIN32)
#define EXPORT __declspec(dllexport)
#else
#define EXPORT
#endif
EXPORT whcar_t w = L'W';
EXPORT wchar_t s[] = L"hello world";
EXPORT wchar_t **str = (wchar_t **)(&s);
```
``` js
var ref = require('ref');
var dlfcn = require('dlfcn');
var wchar_t = require('ref-wchar');
var wchar_string = wchar_t.string;
var lib = dlfcn('./libexample');
// get the "w" symbol as a wchar
var w = lib.get('w', wchar_t.size);
ref.get(w, wchar_t);
// "W"
// get the "s" symbol as a wide string
var s = ref.reinterpretUntilZeros(lib.get('s'), wchar_t.size);
wchar_t.toString(s);
// "hello world"
// get the "str" pointer symbol as a wide string
var str = lib.get('str', wchar_string.size);
ref.get(str, wchar_string);
// "hello world"
```
