Use an INI file in C on Linux
Is there a standard way of reading a kind of configuration like INI files for Linux using C?
I am working on a Linux based handheld and writing code in C.
Otherwise, I shall like to know about any alternatives.
Final update:
I have explored and even used LibConfig. But the footprint is high and my usage is too simple. So, to reduce the footprint, I have rolled out my own implementation. The implementation is not too generic, in fact quite coupled as of now. The configuration file is parsed once at the time of starting the application and set to some global variables.
Answer
Try libconfig:
a simple library for processing structured configuration files, like this one: test.cfg. This file format is more compact and more readable than XML. And unlike XML, it is type-aware, so it is not necessary to do string parsing in application code.
Libconfig is very compact — a fraction of the size of the expat XML parser library. This makes it well-suited for memory-constrained systems like handheld devices.
The library includes bindings for both the C and C++ languages. It works on POSIX-compliant UNIX and UNIX-like systems (GNU/Linux, Mac OS X, Solaris, FreeBSD), Android, and Windows (2000, XP and later)...
