New submission from Alexander Patrakov:

See the example at https://docs.python.org/2/library/socket.html#socket.getaddrinfo

>>> socket.getaddrinfo("www.python.org", 80, 0, 0, socket.SOL_TCP)

As I am primarily a C programmer, it is quite surprising for me to see a SOL_* being passed into the proto argument. I thought that SOL_* is only for setsockopt(), and IPPROTO_* would be suitable. Yes, for TCP and UDP the SOL_* and IPPROTO_* constants are the same, but see e.g. http://msdn.microsoft.com/en-us/library/windows/desktop/ms737530%28v=vs.85%29.aspx which specifically points out that IPPROTO_* constants as acceptable values.
