-- Userdata representing a process created by `spawn()`.
module('proc')
---
-- Returns the status of process *proc*, which is either "running" or
-- "terminated".
-- @param proc A process created by `spawn()`.
-- @return "running" or "terminated"
function status(proc) end
---
-- Blocks until process *proc* finishes.
-- @param proc A process created by `spawn()`.
function wait(proc) end
---
-- Reads and returns stdout from process *proc*, according to string format or
-- number *arg*.
-- Similar to Lua's `io.read()` and blocks for input. *proc* must still be
-- running. If an error occurs while reading, returns `nil`, an error code, and
-- an error message.
-- Ensure any read operations read all stdout available. The stdout callback
-- function passed to `spawn()` will not be called until the stdout buffer is
-- clear.
-- @param proc A process created by `spawn()`.
-- @param arg Optional argument similar to those in Lua's `io.read()`, but "*n"
-- is not supported. The default value is "*l", which reads a line.
-- @return string of bytes read
function read(proc, arg) end
---
-- Writes string input to the stdin of process *proc*.
-- @param proc A process created by `spawn()`.
-- @param ... Standard input for *proc*.
function write(proc, ...) end

-- Kills running process *proc*.
-- @param proc A running process created by `spawn()`.
