    About stdlib...
  </summary>
  <p>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.</p>
  <p>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.</p>
  <p>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.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/regexp-unc-path
```

</section>

<section class="usage">

## Usage

```javascript
var reUncPath = require( '@stdlib/regexp-unc-path' );
```

#### reUncPath()

Returns a [regular expression][regexp] to parse a [UNC][unc] path.

```javascript
var RE_UNC_PATH = reUncPath();
var parts = RE_UNC_PATH.exec( '\\\\server\\share\\foo\\bar\\baz:a:b' );
/* returns
    [
        '\\\\server\\share\\foo\\bar\\baz:a:b',
        'server',                                // host name
        'share',                                 // share name
        '\\foo\\bar\\baz:a:b',                   // object name
        '\\foo\\bar',                            // path name
        'baz:a:b',                               // file name

        'index': 0,
        'input': '\\\\server\\share\\foo\\bar\\baz:a:b'
    ]

parts = RE_UNC_PATH.exec( '\\\\server\\share' );
/* returns
    [
        '\\\\server\\share',

        'input': '\\\\server\\share'
    ]
*/
```

#### reUncPath.REGEXP

[Regular expression][regexp] to parse a [UNC][unc] path.

```javascript
var parts = reUncPath.REGEXP.exec( '\\\\server\\share\\foo\\bar\\baz' )[ 1 ];
// returns 'server'
```
