luerl_io (luerl v1.5.1)

This module provides a standard of set io functions for Luerl. In the following description, many functions have an optional parameter IoDevice. If included, it must be the pid of a process which handles the IO protocols such as the IoDevice returned by file:open/2. Also in the functions handling files it can also be the name of the file which will then be opened.

Note that Luerl, following Lua, does do any implicit UTF-8 encoding of input strings.
