+--- The `options.stdio` entries can take many shapes.
+---
+---   - If they are numbers, then the child process inherits that same zero-indexed fd from the parent process.
+---   - If `uv_stream_t` handles are passed in, those are used as a read-write pipe or inherited stream depending if the stream has a valid fd.
+---   - Including `nil` placeholders means to ignore that fd in the child process.

+
+--- The luv project provides access to the multi-platform support library
+--- libuv in Lua code. It was primarily developed for the luvit project as
+--- the built-in `uv` module, but can be used in other Lua environments.
+---
+--- More information about the core libuv library can be found at the original
+--- libuv documentation page.
+---
+---
+--- Here is a small example showing a TCP echo server:
+---
+--- ```lua
+--- local uv = require("luv") -- "luv" when stand-alone, "uv" in luvi apps
+---
+--- local server = uv.new_tcp()
+--- server:bind("127.0.0.1", 1337)
+--- server:listen(128, function (err)
+---   assert(not err, err)
+---   local client = uv.new_tcp()
+---   server:accept(client)
+---   client:read_start(function (err, chunk)
+---     assert(not err, err)
+---     if chunk then
+---       client:write(chunk)
+---     else
+---       client:shutdown()
+---       client:close()
+---     end
+---   end)
+--- end)
+--- print("TCP server listening at 127.0.0.1 port 1337")
+--- uv.run() -- an explicit run call is necessary outside of luvit
+--- ```
+---
+---
+--- The luv library contains a single Lua module referred to hereafter as `uv` for
+--- simplicity. This module consists mostly of functions with names corresponding to
+--- their original libuv versions. For example, the libuv function `uv_tcp_bind` has
+--- a luv version at `uv.tcp_bind`. Currently, only one non-function field exists:
+--- `uv.constants`, which is a table.
+---
+---
+--- In addition to having simple functions, luv provides an optional method-style
+--- API. For example, `uv.tcp_bind(server, host, port)` can alternatively be called
+--- as `server:bind(host, port)`. Note that the first argument `server` becomes the
+--- object and `tcp_` is removed from the function name. Method forms are
+--- documented below where they exist.
+---
+---
+--- Functions that accept a callback are asynchronous. These functions may
+--- immediately return results to the caller to indicate their initial status, but
+--- their final execution is deferred until at least the next libuv loop iteration.
+--- After completion, their callbacks are executed with any results passed to it.
+---
+--- Functions that do not accept a callback are synchronous. These functions
+--- immediately return their results to the caller.
+---
+--- Some (generally FS and DNS) functions can behave either synchronously or
+--- asynchronously. If a callback is provided to these functions, they behave
+--- asynchronously; if no callback is provided, they behave synchronously.
+---
+---
+--- Some unique types are defined. These are not actual types in Lua, but they are
+--- used here to facilitate documenting consistent behavior:
+--- - `fail`: an assertable `nil, string, string` tuple (see Error handling)
+--- - `callable`: a `function`; or a `table` or `userdata` with a `__call`
+---   metamethod
+--- - `buffer`: a `string` or a sequential `table` of `string`s
+--- - `threadargs`: variable arguments (`...`) of type `nil`, `boolean`, `number`,
+---   `string`, or `userdata`
+---
+---
+--- This documentation is mostly a retelling of the libuv API documentation
+--- within the context of luv's Lua API. Low-level implementation details and
+--- unexposed C functions and types are not documented here except for when they
+--- are relevant to behavior seen in the Lua module.
+---
+--- [Error handling]: #error-handling
+---
+--- In libuv, errors are negative numbered constants; however, these errors and the
+--- functions used to handle them are not exposed to luv users. Instead, if an
+--- internal error is encountered, the luv function will return to the caller an
+--- assertable `nil, err, name` tuple.
+---
+--- - `nil` idiomatically indicates failure
+--- - `err` is a string with the format `{name}: {message}`
+---   - `{name}` is the error name provided internally by `uv_err_name`
+---   - `{message}` is a human-readable message provided internally by `uv_strerror`
+--- - `name` is the same string used to construct `err`
+---
+--- This tuple is referred to below as the `fail` pseudo-type.
+---
+--- When a function is called successfully, it will return either a value that is
+--- relevant to the operation of the function, or the integer `0` to indicate
+--- success, or sometimes nothing at all. These cases are documented below.
+---
+---
+--- [reference counting]: #reference-counting
+---
+--- The libuv event loop (if run in the default mode) will run until there are no
+--- active and referenced handles left. The user can force the loop to exit early by
+--- unreferencing handles which are active, for example by calling `uv.unref()`
+--- after calling `uv.timer_start()`.
+---
+--- A handle can be referenced or unreferenced, the refcounting scheme doesn't use a
+--- counter, so both operations are idempotent.
+---
+--- All handles are referenced when active by default, see `uv.is_active()` for a
+--- more detailed explanation on what being active involves.
+---
+---
+--- [File system operations]: #file-system-operations
+---
+--- Most file system functions can operate synchronously or asynchronously. When a synchronous version is called (by omitting a callback), the function will
+--- immediately return the results of the FS call. When an asynchronous version is
+--- called (by providing a callback), the function will immediately return a
+--- `uv_fs_t userdata` and asynchronously execute its callback; if an error is encountered, the first and only argument passed to the callback will be the `err` error string; if the operation completes successfully, the first argument will be `nil` and the remaining arguments will be the results of the FS call.
+---
+--- Synchronous and asynchronous versions of `readFile` (with naive error handling)
+--- are implemented below as an example:
+---
+--- ```lua
+--- local function readFileSync(path)
+---   local fd = assert(uv.fs_open(path, "r", 438))
+---   local stat = assert(uv.fs_fstat(fd))
+---   local data = assert(uv.fs_read(fd, stat.size, 0))
+---   assert(uv.fs_close(fd))
+---   return data
+--- end
+---
+--- local data = readFileSync("main.lua")
+--- print("synchronous read", data)
+--- ```
+---
+--- ```lua
+--- local function readFile(path, callback)
+---   uv.fs_open(path, "r", 438, function(err, fd)
+---     assert(not err, err)
+---     uv.fs_fstat(fd, function(err, stat)
+---       assert(not err, err)
+---       uv.fs_read(fd, stat.size, 0, function(err, data)
+---         assert(not err, err)
+---         uv.fs_close(fd, function(err)
+---           assert(not err, err)
+---           return callback(data)
+---         end)
+---       end)
+---     end)
+---   end)
+--- end
+---
+--- readFile("main.lua", function(data)
+---   print("asynchronous read", data)
+--- end)
+--- ```
+---
+---
+--- [Thread pool work scheduling]: #thread-pool-work-scheduling
+---
+--- Libuv provides a threadpool which can be used to run user code and get notified
+--- in the loop thread. This threadpool is internally used to run all file system
+--- operations, as well as `getaddrinfo` and `getnameinfo` requests.
+---
+--- ```lua
+--- local function work_callback(a, b)
+---   return a + b
+--- end
+---
+--- local function after_work_callback(c)
+---   print("The result is: " .. c)
+--- end
+---
+--- local work = uv.new_work(work_callback, after_work_callback)
+---
+--- work:queue(1, 2)
+---
+--- -- output: "The result is: 3"
+--- ```
+---
+---
+--- [DNS utility functions]: #dns-utility-functions
+---
+---
+--- [Threading and synchronization utilities]: #threading-and-synchronization-utilities
+---
+--- Libuv provides cross-platform implementations for multiple threading an
+---  synchronization primitives. The API largely follows the pthreads API.
+---
+---
+--- [Miscellaneous utilities]: #miscellaneous-utilities
+---
+---
+--- [Metrics operations]: #metrics-operations

+---   - `"metrics_idle_time"`: Accumulate the amount of idle time the event loop spends
+---   in the event provider. This option is necessary to use `metrics_idle_time()`.
+---
+--- An example of a valid call to this function is:
+---
+--- ```lua

+--- Retrieve the amount of time the event loop has been idle in the kernel’s event

+--- The return value is the accumulated time spent idle in the kernel’s event

+---
+--- **Note:** The event loop will not begin accumulating the event provider’s idle

+--- The `options` table accepts the following fields:

+---   which concatenates the arguments into a string. This can cause some strange
+---   errors. (See `options.verbatim` below for Windows.)
+---   - `options.stdio` - Set the file descriptors that will be made available to
+---   the child process. The convention is that the first entries are stdin, stdout,
+---   and stderr. (**Note**: On Windows, file descriptors after the third are
+---   available to the child process only if the child processes uses the MSVCRT
+---   runtime.)
+---   - `options.env` - Set environment variables for the new process.
+---   - `options.cwd` - Set the current working directory for the sub-process.
+---   - `options.uid` - Set the child process' user id.
+---   - `options.gid` - Set the child process' group id.
+---   - `options.verbatim` - If true, do not wrap any arguments in quotes, or
+---   perform any other escaping, when converting the argument list into a command
+---   line string. This option is only meaningful on Windows systems. On Unix it is
+---   silently ignored.
+---   - `options.detached` - If true, spawn the child process in a detached state -
+---   this will make it a process group leader, and will effectively enable the
+---   child to keep running after the parent exits. Note that the child process
+---   will still keep the parent's event loop alive unless the parent process calls
+---   `uv.unref()` on the child's process handle.
+---   - `options.hide` - If true, hide the subprocess console window that would
+---   normally be created. This option is only meaningful on Windows systems. On
+---   Unix it is silently ignored.
+---
+--- The `options.stdio` entries can take many shapes.
+---
+---   - If they are numbers, then the child process inherits that same zero-indexed
+---   fd from the parent process.
+---   - If `uv_stream_t` handles are passed in, those are used as a read-write pipe
+---   or inherited stream depending if the stream has a valid fd.
+---   - Including `nil` placeholders means to ignore that fd in the child process.

+
+--- Poll handles are used to watch file descriptors for readability and writability,
+--- similar to the purpose of [poll(2)](http://linux.die.net/man/2/poll).
+---
+--- The purpose of poll handles is to enable integrating external libraries that
+--- rely on the event loop to signal it about the socket status changes, like c-ares
+--- or libssh2. Using `uv_poll_t` for any other purpose is not recommended;
+--- `uv_tcp_t`, `uv_udp_t`, etc. provide an implementation that is faster and more
+--- scalable than what can be achieved with `uv_poll_t`, especially on Windows.
+---
+--- It is possible that poll handles occasionally signal that a file descriptor is
+--- readable or writable even when it isn't. The user should therefore always be
+--- prepared to handle EAGAIN or equivalent when it attempts to read from or write
+--- to the fd.
+---
+--- It is not okay to have multiple active poll handles for the same socket, this
+--- can cause libuv to busyloop or otherwise malfunction.
+---
+--- The user should not close a file descriptor while it is being polled by an
+--- active poll handle. This can cause the handle to report an error, but it might
+--- also start polling another socket. However the fd can be safely closed
+--- immediately after a call to `poll:stop()` or `uv.close()`.
+---
+--- **Note**: On windows only sockets can be polled with poll handles. On Unix any
+--- file descriptor that would be accepted by poll(2) can be used.

+--- As soon as an event is detected the callback will be called with status set to 0, and the detected events set on the events field.
+---
+--- The user should not close the socket while the handle is active. If the user
+--- does that anyway, the callback may be called reporting an error status, but this

+--- Signal handles implement Unix style signal handling on a per-event loop bases.
+---
+--- **Unix Notes:**
+---
+--- - SIGKILL and SIGSTOP are impossible to catch.
+---
+--- - Handling SIGBUS, SIGFPE, SIGILL or SIGSEGV via libuv results into undefined behavior.
+---
+--- - SIGABRT will not be caught by libuv if generated by abort(), e.g. through assert().
+---
+--- - On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL pthreads library to manage threads. Installing watchers for those signals will lead to unpredictable behavior and is strongly discouraged. Future versions of libuv may simply reject them.
+---
+--- **Windows Notes:**
+---
+--- Reception of some signals is emulated on Windows:
+--- - SIGINT is normally delivered when the user presses CTRL+C. However, like on Unix, it is not generated when terminal raw mode is enabled.
+---
+--- - SIGBREAK is delivered when the user pressed CTRL + BREAK.
+---
+--- - SIGHUP is generated when the user closes the console window. On SIGHUP the program is given approximately 10 seconds to perform cleanup. After that Windows will unconditionally terminate it.
+---
+--- - SIGWINCH is raised whenever libuv detects that the console has been resized. SIGWINCH is emulated by libuv when the program uses a uv_tty_t handle to write to the console. SIGWINCH may not always be delivered in a timely manner; libuv will only detect size changes when the cursor is being moved. When a readable `uv_tty_t` handle is used in raw mode, resizing the console buffer will also trigger a SIGWINCH signal.
+---
+--- - Watchers for other signals can be successfully created, but these signals are never received. These signals are: SIGILL, SIGABRT, SIGFPE, SIGSEGV, SIGTERM and SIGKILL.
+---
+--- - Calls to raise() or abort() to programmatically raise a signal are not detected by libuv; these will not trigger a signal watcher.
