Questions tagged [libconfig]

Libconfig is a simple library for processing structured configuration files. 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. 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).
