I have a socket descriptor descriptor, which has been initialized by either of the following:
- int descriptor = socket(PF_INET, SOCK_STREAM, 0);
- int descriptor = socket(PF_INET6, SOCK_STREAM, 0);

But I don't know which of the two. I would like to determine whether the socket corresponding to descriptor is an IPv4 or an IPv6 socket. I know that, for example, one can use getsockopt to determine the socket type (e.g., SOCK_STREAM vs SOCK_DGRAM) but I cannot seem to find a way to determine the socket domain (e.g., PF_INET vs PF_INET6).

  What is your platform? In linux, you can do getsockopt(SO_DOMAIN). See man 7 socket for details.
