52 When a socket is created
55 it exists in an address family space but has no protocol address assigned.

61 Binding an address in the

64 system that must be deleted by the caller when it is no longer
68 The rules used in address binding vary between communication domains.
69 Consult the manual entries in section 4 for detailed information.
71 For maximum portability, you should always zero the socket address structure
