%description
The files dht.c and dht.h implement the variant of the Kademlia Distributed
Hash Table (DHT) used in the Bittorrent network (``mainline'' variant).

The file dht-example.c is a stand-alone program that participates in the
DHT.  Another example is a patch against Transmission, which you might or
might not be able to find somewhere.

The code is designed to work well in both event-driven and threaded code.
The caller, which is either an event-loop or a dedicated thread, must
periodically call the function dht_periodic.  In addition, it must call
dht_periodic whenever any data has arrived from the network.

All functions return -1 in case of failure, in which case errno is set, or
a positive value in case of success.
