|
|
* \brief This class reads an INI file into easy-to-access name/value pairs.
|
|
* \author Brush Technologies, 2009.
|
|
*
|
|
* inih (INI Not Invented Here) is a simple .INI file parser written in C++.
|
|
* It's only a couple of pages of code, and it was designed to be small
|
|
* and simple, so it's good for embedded systems. To use it, just give
|
|
* ini_parse() an INI file, and it will call a callback for every
|
|
* name=value pair parsed, giving you strings for the section, name,
|
|
* and value. It's done this way because it works well on low-memory
|
|
* embedded systems, but also because it makes for a KISS implementation.
