Why are the size variables in libc/resolv/inet_ntop.c of type socklen_t instead
of size_t while in fact they have nothing to do with any socket structures?

I ask about this because I just had a proble when I read the header file and the
manual (*not* carefuly enough) and put *thoughtlessly* sizeof(struct sockaddr)
as fourth argument.  Of course it didn't work.

Indeed now for me this is only a matter of clarity but please answer.

Note that the info page for inet_ntop() shows the wrong prototype.  The last
argument should be shown with the type socklen_t, not size_t.  The info page
should be fixed.
