Consuming a UDPStreamer feed so far meant either linking MARTe2 (UDPSClient) or writing Go (Common/Client/go/udpsprotocol). Common/Client/c fills the gap for plain C/C++ integrators: two files depending on nothing but libc and BSD sockets, covering the whole receive path — CONNECT, fragment reassembly, CONFIG/DATA decoding with dequantisation, keepalives and silence-triggered reconnect. No threads are spawned; udps_client_poll() does all the work and runs every callback, so it drops into an existing event loop unsynchronised. Verified against run_udp_producer.sh at 1 Msps: unicast (120 MiB, no loss) and multicast with 12-fragment cycles (116k datagrams, no loss). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
