** The pipe library also supports the automatic scheduling of a reader task. This

** reader automatically reschedules itself if the pipe contains unread content.
**
** The reader tasks may be interleaved with other tasks that write to the pipe and
** others that don't. Any task writing to the pipe will also trigger the posting
** of a read task if one is not already pending. In this way at most only one
** pending reader task is pending, and this prevents overrun of the task queueing
** system.
**
** Implementation Notes:
**
** - The Pipe slot 1 is used to store the Lua CB function reference of the reader
** task. Note that is actually an auxiliary wrapper around the supplied Lua CB
** function, and this wrapper also uses upvals to store internal pipe state.
** The remaining slots are the Userdata buffer chunks.
**
** - This internal state needs to be shared with the pipe_write function, but a
** limitation of Lua 5.1 is that C functions cannot share upvals; to avoid this
** constraint, this function is also denormalised to act as the pipe_write
** function: if Arg1 is the pipe then its a pipe:write() otherwise its a
** CB wrapper.
**
** Also note that the pipe module is used by the Lua VM and therefore the create
** read, and unread methods are exposed as directly callable C functions. (Write
** is available throogh pipe[1].)

## node.output() ## node.output()
Redirects the Lua interpreter output to a callback function. Optionally also prints it to the serial console. Redirects the Lua interpreter to a `stdout` pipe when a CB function is specified (See `pipe` module) and resets output to normal otherwise. Optionally also prints to the serial console.
!!! caution
Do **not** attempt to `print()` or otherwise induce the Lua interpreter to produce output from within the callback function. Doing so results in infinite recursion, and leads to a watchdog-triggered restart.

#### Parameters #### Parameters
- `output_fn(str)` a function accept every output as str, and can send the output to a socket (or maybe a file). - `output_fn(pipe)` a function accept every output as str, and can send the output to a socket (or maybe a file). Note that this function must conform to the fules for a pipe reader callback.
