About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> [Regular expression][regexp] to detect an [extended-length path][extended-length-path].
## Installation
```bash
npm install @stdlib/regexp-extended-length-path
```
Alternatively,
- To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]).
- If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions).
- For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]).
The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
## 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
```
