51 assigns the local protocol address to a socket.
52 When a socket is created
55 it exists in an address family space but has no protocol address assigned.
59 be assigned to the socket.
61 Binding an address in the UNIX domain creates a socket in the file
62 system that must be deleted by the caller when it is no longer
66 The rules used in address binding vary between communication domains.
67 Consult the manual entries in section 4 for detailed information.
69 For maximum portability, you should always zero the socket address structure
70 before populating it and passing it to
80 Kernel resources to complete the request are
81 temporarily unavailable.

88 .It Bq Er EADDRNOTAVAIL
89 The specified address is not available from the local machine.
91 The specified address is already in use.
93 The requested address is protected, and the current user
94 has inadequate permission to access it.

107 A component of a pathname exceeded 255 characters,
