P.S., in the networking world, it is called a port number.
Errr...no. Port numbers are relatively static, and the port numbers for
Well Known Services are likely to be defined in /etc/services. Socket
numbers are dynamic. So the well known port number for SMTP is
25, and if a process were to make two connections to port 25 (unusual,
and perhaps a bad idea) those connections would get different socket
numbers, neither of which is likely to be 25.
Not to mention that port numbers are short integers (half-words).

A socket descriptor (which seems to be a fancy name for a number) is 4 bytes.
