// Officially, to be more SDL-like, we ought to arrange our structures with particular alignment,
// specify C-style linkage, etc.  I don't think that's important at this point, but should anyone be
// deranged enough to detach SDL_netx from Aleph One and position it as a real extension to SDL_net,
// these things should be investigated.

//   outputs: return value - positive if broadcasting was enabled; 0 if not
