[Question] is dns_domain_length() really working?

[pierre-rouleau]

Hi @henryk, thanks for this repo.

The file dns_domain.c has some code that puzzles me. I might be tired, but that code does not seem to work:

unsigned int dns_domain_length(const char *dn)
{
  const char *x;
  unsigned char c;

  x = dn;
  while (c = *x++)
    x += (unsigned int) c;
  return x - dn;
}

Why is this adding the value of the c to the pointer x? is dn pointing to some sort of structure that is not a real C string, a sequence of characters?
