You can use https://github.com/paullouisageneau/libdatachannel for your C/C++ integration needs. It's 10k lines. So the answer is 0. Its required dependencies (I assume this as they are git submodules in deps) are more than 100k lines, though, srtp support making the bulk of it. On my machine it took 11 seconds to compile it.
Irssi is 64k lines (plus its dependencies), so I guess that makes WebRTC complicated.
Can't argue that DCC isn't simple, but perhaps the protocol deviced decades ago is a bit too simple.
