+/**
+ * `Buffer` objects are used to represent a fixed-length sequence of bytes. Many
+ * Node.js APIs support `Buffer`s.
+ *
+ * The `Buffer` class is a subclass of JavaScript's [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) class and
+ * extends it with methods that cover additional use cases. Node.js APIs accept
+ * plain [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) s wherever `Buffer`s are supported as well.
+ *
+ * While the `Buffer` class is available within the global scope, it is still
+ * recommended to explicitly reference it via an import or require statement.
+ *
+ * ```js
+ * import { Buffer } from 'node:buffer';
+ *
+ * // Creates a zero-filled Buffer of length 10.
+ * const buf1 = Buffer.alloc(10);
+ *
+ * // Creates a Buffer of length 10,
+ * // filled with bytes which all have the value `1`.
+ * const buf2 = Buffer.alloc(10, 1);
+ *
+ * // Creates an uninitialized buffer of length 10.
+ * // This is faster than calling Buffer.alloc() but the returned
+ * // Buffer instance might contain old data that needs to be
+ * // overwritten using fill(), write(), or other functions that fill the Buffer's
+ * // contents.
+ * const buf3 = Buffer.allocUnsafe(10);
+ *
+ * // Creates a Buffer containing the bytes [1, 2, 3].
+ * const buf4 = Buffer.from([1, 2, 3]);
+ *
+ * // Creates a Buffer containing the bytes [1, 1, 1, 1] – the entries
+ * // are all truncated using `(value & 255)` to fit into the range 0–255.
+ * const buf5 = Buffer.from([257, 257.5, -255, '1']);
+ *
+ * // Creates a Buffer containing the UTF-8-encoded bytes for the string 'tést':
+ * // [0x74, 0xc3, 0xa9, 0x73, 0x74] (in hexadecimal notation)
+ * // [116, 195, 169, 115, 116] (in decimal notation)
+ * const buf6 = Buffer.from('tést');
+ *
+ * // Creates a Buffer containing the Latin-1 bytes [0x74, 0xe9, 0x73, 0x74].

+ * _initialized_. The contents of the newly created `Buffer` are unknown and _may contain sensitive data_. Use `buf.fill(0)` to initialize
+ * such `Buffer` instances with zeroes.
+ *
+ * When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+ * allocations under 4 KiB are sliced from a single pre-allocated `Buffer`. This

+ * performance and memory usage by eliminating the need to track and clean up as
+ * many individual `ArrayBuffer` objects.
+ *
+ * However, in the case where a developer may need to retain a small chunk of
+ * memory from a pool for an indeterminate amount of time, it may be appropriate
+ * to create an un-pooled `Buffer` instance using `Buffer.allocUnsafeSlow()` and
+ * then copying out the relevant bits.
+ *
+ * ```js
+ * import { Buffer } from 'node:buffer';
+ *
+ * // Need to keep around a few small chunks of memory.
+ * const store = [];
+ *
+ * socket.on('readable', () => {

+/**
+ * The `child_process` module provides the ability to spawn subprocesses in
+ * a manner that is similar, but not identical, to [`popen(3)`](http://man7.org/linux/man-pages/man3/popen.3.html). This capability
+ * is primarily provided by the {@link spawn} function:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const ls = spawn('ls', ['-lh', '/usr']);
+ *
+ * ls.stdout.on('data', (data) => {
+ * console.log(`stdout: ${data}`);
+ * });
+ *
+ * ls.stderr.on('data', (data) => {
+ * console.error(`stderr: ${data}`);
+ * });
+ *
+ * ls.on('close', (code) => {
+ * console.log(`child process exited with code ${code}`);
+ * });
+ * ```
+ *
+ * By default, pipes for `stdin`, `stdout`, and `stderr` are established between
+ * the parent Node.js process and the spawned subprocess. These pipes have
+ * limited (and platform-specific) capacity. If the subprocess writes to
+ * stdout in excess of that limit without the output being captured, the
+ * subprocess blocks waiting for the pipe buffer to accept more data. This is
+ * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }`option if the output will not be consumed.
+ *
+ * The command lookup is performed using the `options.env.PATH` environment
+ * variable if `env` is in the `options` object. Otherwise, `process.env.PATH` is
+ * used. If `options.env` is set without `PATH`, lookup on Unix is performed
+ * on a default search path search of `/usr/bin:/bin` (see your operating system's
+ * manual for execvpe/execvp), on Windows the current processes environment
+ * variable `PATH` is used.
+ *
+ * On Windows, environment variables are case-insensitive. Node.js
+ * lexicographically sorts the `env` keys and uses the first one that
+ * case-insensitively matches. Only first (in lexicographic order) entry will be
+ * passed to the subprocess. This might lead to issues on Windows when passing
+ * objects to the `env` option that have multiple variants of the same key, such as`PATH` and `Path`.
+ *
+ * The {@link spawn} method spawns the child process asynchronously,
+ * without blocking the Node.js event loop. The {@link spawnSync} function provides equivalent functionality in a synchronous manner that blocks
+ * the event loop until the spawned process either exits or is terminated.
+ *
+ * For convenience, the `child_process` module provides a handful of synchronous
+ * and asynchronous alternatives to {@link spawn} and {@link spawnSync}. Each of these alternatives are implemented on
+ * top of {@link spawn} or {@link spawnSync}.
+ *
+ * * {@link exec}: spawns a shell and runs a command within that
+ * shell, passing the `stdout` and `stderr` to a callback function when
+ * complete.
+ * * {@link execFile}: similar to {@link exec} except
+ * that it spawns the command directly without first spawning a shell by
+ * default.

+ * When an IPC channel has been established between the parent and child (
+ * i.e. when using {@link fork}), the `subprocess.send()` method can
+ * be used to send messages to the child process. When the child process is a
+ * Node.js instance, these messages can be received via the `'message'` event.
+ *
+ * The message goes through serialization and parsing. The resulting
+ * message might not be the same as what is originally sent.
+ *
+ * For example, in the parent script:
+ *
+ * ```js
+ * const cp = require('child_process');
+ * const n = cp.fork(`${__dirname}/sub.js`);
+ *
+ * n.on('message', (m) => {
+ * console.log('PARENT got message:', m);
+ * });
+ *
+ * // Causes the child to print: CHILD got message: { hello: 'world' }
+ * n.send({ hello: 'world' });
+ * ```
+ *
+ * And then the child script, `'sub.js'` might look like this:
+ *
+ * ```js
+ * process.on('message', (m) => {
+ * console.log('CHILD got message:', m);
+ * });
+ *
+ * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null }
+ * process.send({ foo: 'bar', baz: NaN });
+ * ```
+ *
+ * Child Node.js processes will have a `process.send()` method of their own
+ * that allows the child to send messages back to the parent.
+ *
+ * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages
+ * containing a `NODE_` prefix in the `cmd` property are reserved for use within
+ * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js.
+ * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice.
+ *
+ * The optional `sendHandle` argument that may be passed to `subprocess.send()` is
+ * for passing a TCP server or socket object to the child process. The child will
+ * receive the object as the second argument passed to the callback function
+ * registered on the `'message'` event. Any data that is received
+ * and buffered in the socket will not be sent to the child.
+ *
+ * The optional `callback` is a function that is invoked after the message is
+ * sent but before the child may have received it. The function is called with a
+ * single argument: `null` on success, or an `Error` object on failure.
+ *
+ * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can
+ * happen, for instance, when the child process has already exited.
+ *
+ * `subprocess.send()` will return `false` if the channel has closed or when the
+ * backlog of unsent messages exceeds a threshold that makes it unwise to send
+ * more. Otherwise, the method returns `true`. The `callback` function can be
+ * used to implement flow control.
+ *
+ * #### Example: sending a server object
+ *
+ * The `sendHandle` argument can be used, for instance, to pass the handle of
+ * a TCP server object to the child process as illustrated in the example below:
+ *
+ * ```js
+ * const subprocess = require('child_process').fork('subprocess.js');
+ *
+ * // Open up the server object and send the handle.
+ * const server = require('net').createServer();
+ * server.on('connection', (socket) => {
+ * socket.end('handled by parent');
+ * });
+ * server.listen(1337, () => {
+ * subprocess.send('server', server);
+ * });
+ * ```
+ *
+ * The child would then receive the server object as:
+ *
+ * ```js
+ * process.on('message', (m, server) => {
+ * if (m === 'server') {
+ * server.on('connection', (socket) => {
+ * socket.end('handled by child');
+ * });
+ * }
+ * });
+ * ```
+ *
+ * Once the server is now shared between the parent and child, some connections
+ * can be handled by the parent and some by the child.
+ *
+ * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on
+ * a `'message'` event instead of `'connection'` and using `server.bind()` instead
+ * of `server.listen()`. This is, however, currently only supported on Unix
+ * platforms.
+ *
+ * #### Example: sending a socket object
+ *
+ * Similarly, the `sendHandler` argument can be used to pass the handle of a
+ * socket to the child process. The example below spawns two children that each
+ * handle connections with "normal" or "special" priority:
+ *
+ * ```js
+ * const { fork } = require('child_process');
+ * const normal = fork('subprocess.js', ['normal']);
+ * const special = fork('subprocess.js', ['special']);
+ *
+ * // Open up the server and send sockets to child. Use pauseOnConnect to prevent
+ * // the sockets from being read before they are sent to the child process.
+ * const server = require('net').createServer({ pauseOnConnect: true });
+ * server.on('connection', (socket) => {
+ *
+ * // If this is special priority...
+ * if (socket.remoteAddress === '74.125.127.100') {
+ * special.send('socket', socket);
+ * return;
+ * }
+ * // This is normal priority.
+ * normal.send('socket', socket);
+ * });
+ * server.listen(1337);
+ * ```
+ *
+ * The `subprocess.js` would receive the socket handle as the second argument
+ * passed to the event callback function:
+ *
+ * ```js
+ * process.on('message', (m, socket) => {
+ * if (m === 'socket') {
+ * if (socket) {
+ * // Check that the client socket exists.
+ * // It is possible for the socket to be closed between the time it is
+ * // sent and the time it is received in the child process.
+ * socket.end(`Request handled with ${process.argv[2]} priority`);
+ * }
+ * }
+ * });
+ * ```
+ *
+ * Do not use `.maxConnections` on a socket that has been passed to a subprocess.
+ * The parent cannot track when the socket is destroyed.
+ *
+ * Any `'message'` handlers in the subprocess should verify that `socket` exists,
+ * as the connection may have been closed during the time it takes to send the
+ * connection to the child.
+ * @since v0.5.9

+ * Example of running `ls -lh /usr`, capturing `stdout`, `stderr`, and the
+ * exit code:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const ls = spawn('ls', ['-lh', '/usr']);
+ *
+ * ls.stdout.on('data', (data) => {
+ * console.log(`stdout: ${data}`);
+ * });
+ *
+ * ls.stderr.on('data', (data) => {
+ * console.error(`stderr: ${data}`);
+ * });
+ *
+ * ls.on('close', (code) => {
+ * console.log(`child process exited with code ${code}`);
+ * });
+ * ```
+ *
+ * Example: A very elaborate way to run `ps ax | grep ssh`
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const ps = spawn('ps', ['ax']);
+ * const grep = spawn('grep', ['ssh']);
+ *
+ * ps.stdout.on('data', (data) => {
+ * grep.stdin.write(data);
+ * });
+ *
+ * ps.stderr.on('data', (data) => {
+ * console.error(`ps stderr: ${data}`);
+ * });
+ *
+ * ps.on('close', (code) => {
+ * if (code !== 0) {
+ * console.log(`ps process exited with code ${code}`);
+ * }
+ * grep.stdin.end();
+ * });
+ *
+ * grep.stdout.on('data', (data) => {
+ * console.log(data.toString());
+ * });
+ *
+ * grep.stderr.on('data', (data) => {
+ * console.error(`grep stderr: ${data}`);
+ * });
+ *
+ * grep.on('close', (code) => {
+ * if (code !== 0) {
+ * console.log(`grep process exited with code ${code}`);
+ * }
+ * });
+ * ```
+ *
+ * Example of checking for failed `spawn`:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const subprocess = spawn('bad_command');
+ *
+ * subprocess.on('error', (err) => {
+ * console.error('Failed to start subprocess.');
+ * });
+ * ```
+ *
+ * Certain platforms (macOS, Linux) will use the value of `argv[0]` for the process
+ * title while others (Windows, SunOS) will use `command`.
+ *
+ * Node.js currently overwrites `argv[0]` with `process.execPath` on startup, so`process.argv[0]` in a Node.js child process will not match the `argv0`parameter passed to `spawn` from the parent,
+ * retrieve it with the`process.argv0` property instead.
+ *
+ * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+ * the error passed to the callback will be an `AbortError`:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const controller = new AbortController();
+ * const { signal } = controller;
+ * const grep = spawn('grep', ['ssh'], { signal });
+ * grep.on('error', (err) => {
+ * // This will be called with err being an AbortError if the controller aborts
+ * });
+ * controller.abort(); // Stops the child process
+ * ```
+ * @since v0.1.90
+ * @param command The command to run.
+ * @param args List of string arguments.
