Whoops, thanks, I fixed the function name.

The seed function just conditions the raw seed values you pass in. You can call it with a structure literal, or like

    pcg_t pcg_entropy(void) {
        pcg_t rng;
        if (getentropy(&rng, sizeof(rng)) < 0)
            err(1, "getentropy");
        return (pcg_seed(rng));
    }
