# Extended Length Path
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
> [Regular expression][regexp] to detect an [extended-length path][extended-length-path].
## Installation
```bash
npm install @stdlib/regexp-extended-length-path
```
## Usage
```javascript
var reExtendedLengthPath = require( '@stdlib/regexp-extended-length-path' );
```
#### reExtendedLengthPath()
Returns a [regular expression][regexp] to detect an [extended-length path][extended-length-path] (i.e., a Windows path which begins with the characters `\\?\`).
```javascript
var RE = reExtendedLengthPath();
var bool = RE.test( '\\\\?\\C:\\foo\\bar' );
// returns true
```
## Examples
```javascript
var reExtendedLengthPath = require( '@stdlib/regexp-extended-length-path' );
var RE_EXTENDED_LENGTH_PATH = reExtendedLengthPath();
var bool;
var path;
path = '\\\\?\\C:\\foo\\bar';
bool = RE_EXTENDED_LENGTH_PATH.test( path );
// returns true
path = '\\\\?\\UNC\\server\\share';
bool = RE_EXTENDED_LENGTH_PATH.test( path );
// returns true
path = 'C:\\foo\\bar';
bool = RE_EXTENDED_LENGTH_PATH.test( path );
// returns false
path = '/c/foo/bar';
bool = RE_EXTENDED_LENGTH_PATH.test( path );
// returns false
path = '/foo/bar';
bool = RE_EXTENDED_LENGTH_PATH.test( path );
// returns false
```
