*
* The optional `options.statCheck` function may be specified to give user code

* of the given file:
*
* If an error occurs while attempting to read the file data, the `Http2Stream`will be closed using an `RST_STREAM` frame using the standard `INTERNAL_ERROR`code. If the `onError` callback is

*
* Example using a file path:
*
* ```js
* const http2 = require('http2');
* const server = http2.createServer();
* server.on('stream', (stream) => {
* function statCheck(stat, headers) {
* headers['last-modified'] = stat.mtime.toUTCString();

* // stream.respond() can throw if the stream has been destroyed by
* // the other side.
* try {
* if (err.code === 'ENOENT') {
* stream.respond({ ':status': 404 });
* } else {
* stream.respond({ ':status': 500 });
* }
* } catch (err) {

* stream.end();
* }
*
* stream.respondWithFile('/some/file',
* { 'content-type': 'text/plain; charset=utf-8' },
* { statCheck, onError });
* });
* ```
*
* The `options.statCheck` function may also be used to cancel the send operation
* by returning `false`. For instance, a conditional request may check the stat
* results to determine if the file has been modified to return an appropriate`304` response:
*
* ```js
* const http2 = require('http2');
* const server = http2.createServer();
* server.on('stream', (stream) => {
* function statCheck(stat, headers) {
* // Check the stat here...
* stream.respond({ ':status': 304 });
* return false; // Cancel the send operation
* }
* stream.respondWithFile('/some/file',
* { 'content-type': 'text/plain; charset=utf-8' },
* { statCheck });
* });
* ```
*
* The `content-length` header field will be automatically set.
*
* The `offset` and `length` options may be used to limit the response to a
* specific range subset. This can be used, for instance, to support HTTP Range
* requests.
*
* The `options.onError` function may also be used to handle all the errors
* that could happen before the delivery of the file is initiated. The
* default behavior is to destroy the stream.
*
* When the `options.waitForTrailers` option is set, the `'wantTrailers'` event
* will be emitted immediately after queuing the last chunk of payload data to be
* sent. The `http2stream.sendTrailers()` method can then be used to sent trailing

/**
* Sends a response header to the request. The status code is a 3-digit HTTP
* status code, like `404`. The last argument, `headers`, are the response headers.
*
* Returns a reference to the `Http2ServerResponse`, so that calls can be chained.
*
* For compatibility with `HTTP/1`, a human-readable `statusMessage` may be
* passed as the second argument. However, because the `statusMessage` has no
* meaning within HTTP/2, the argument will have no effect and a process warning
* will be emitted.
*
* ```js
* const body = 'hello world';
* response.writeHead(200, {
* 'Content-Length': Buffer.byteLength(body),
* 'Content-Type': 'text/plain; charset=utf-8',
* });
* ```
*
* `Content-Length` is given in bytes not characters. The`Buffer.byteLength()` API may be used to determine the number of bytes in a
* given encoding. On outbound messages, Node.js does not check if Content-Length
* and the length of the body being transmitted are equal or not. However, when
* receiving messages, Node.js will automatically reject messages when the`Content-Length` does not match the actual payload size.
*
* This method may be called at most one time on a message before `response.end()` is called.
*
* If `response.write()` or `response.end()` are called before calling
* this, the implicit/mutable headers will be calculated and call this function.
*
* When headers have been set with `response.setHeader()`, they will be merged
* with any headers passed to `response.writeHead()`, with the headers passed
* to `response.writeHead()` given precedence.
*
* ```js
* // Returns content-type = text/plain
* const server = http2.createServer((req, res) => {
* res.setHeader('Content-Type', 'text/html; charset=utf-8');
* res.setHeader('X-Foo', 'bar');
* res.writeHead(200, { 'Content-Type': 'text/plain; charset=utf-8' });
* res.end('ok');
* });
* ```
*
* Attempting to set a header field name or value that contains invalid characters
* will result in a `TypeError` being thrown.
