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.

Connecting to 2 hosts and show all contacts

This example will connect to two SBS-1 hosts and will show all the contacted aircrafts on stdout. The library will be initialized with the LHR_AUTOCONNECT flag to immediatly connect to added hosts. New contacted aircrafts will also be written to stdout with a special marker.
The hosts will be added with the LHR_ONAIRCONTACT event listener. So later we must only add the event listener for the LHR_ONCONTACT event.
There is NO CHECK for successfully connects! (This will be done in a different example). This program will run appr. 120 seconds.
