The suffix is appended to this. * `suffix` **{Buffer}**: Buffer that will be appended to the buf. * `returns` **{Buffer}**: Final Buffer **Example** ```js console.log([appendBuffer(new Buffer('abc\r\n'), new Buffer('def')).toString()]); //=> [ 'abc\r\ndef\r\n' ] console.log([appendBuffer(new Buffer('abc\n'), new Buffer('def')).toString()]); //=> [ 'abc\ndef\n' ] // uses os.EOL when a line ending is not found console.log([appendBuffer(new Buffer('abc'), new Buffer('def')).toString()]); //=> [ 'abc\ndef' ] ``` ## Attribution The code in this module was originally added in a [PR](https://github.com/jonschlinkert/file-normalize/pull/3) to [file-normalize](https://github.com/jonschlinkert/file-normalize). It has been split out to allow for standalone use cases. ## About ### Contributing Pull requests and stars are always welcome.
