    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>

# Read File List

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] <!-- [![dependencies][dependencies-image]][dependencies-url] -->

> Read the entire contents of each file in a file list.

<section class="installation">

## Installation

```bash
npm install @stdlib/fs-read-file-list
```

</section>

<section class="usage">

## Usage

```javascript
var readFileList = require( '@stdlib/fs-read-file-list' );
```

#### readFileList( filepaths\[, options], clbk )

Asynchronously reads the entire contents of each file in a file list.

```javascript
readFileList( [ __filename ], onFiles );

function onFiles( error, files ) {
    if ( error ) {
        throw error;
    }
    console.dir( files );
    // => [{...}]
}
```

Each file is represented by an `object` with the following fields:

-   **file**: file path.
-   **data**: file contents as either a [`Buffer`][node-buffer] or `string`.

The function accepts the same options as [`readFile()`][@stdlib/fs/read-file].

#### readFileList.sync( filepaths\[, options] )

Synchronously reads the entire contents of each file in a file list.

```javascript
var out = readFileList.sync( [ __filename ] );
if ( out instanceof Error ) {
    throw out;
}
console.dir( out );
// => [{...}]
```

The function accepts the same options as [`readFile.sync()`][@stdlib/fs/read-file].

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var readFileList = require( '@stdlib/fs-read-file-list' );

/* Sync */

var files = readFileList.sync( [ __filename ], 'utf8' );
// returns <ObjectArray>

console.log( files instanceof Error );
// => false

files = readFileList.sync( [ 'beepboop' ], {
    'encoding': 'utf8'
});
// returns <Error>

console.log( files instanceof Error );
// => true

/* Async */

readFileList( [ __filename ], onFiles );
readFileList( [ 'beepboop' ], onFiles );

function onFiles( error, files ) {
    if ( error ) {
        if ( error.code === 'ENOENT' ) {
            console.error( 'A file does not exist.' );
        } else {
            throw error;
        }
    } else {
        console.dir( files );
    }
}
```
