libhomeradar - easy collect aircraft informations

libhomeradar is an easy to use library for all type of programming language which can use libraries. libhomeradar can connect to different sources to collect aircraft informations arround the world with extended informations, powerful filtering and structured data access.

libhomeradar is written in C and is available for Linux and Windows (2003, XP, NT, Vista).

Currently libhomeradar works with the Kinetic Avionics SBS-1 base station and the Airnav Systems Radarbox.

Here we try to connect to two SBS-1 hosts. All contacted aircrafts will be written to stdout. New contacts will get a special output format. During shutdown of the program the usage statistics from both hosts will be shown. This will be realized with the homeradar_stats() function.
