60 Binding an address in the UNIX domain creates a socket in the file
61 system that must be deleted by the caller when it is no longer
65 The rules used in address binding vary between communication domains.

90 If the bind is successful, a 0 value is returned.

127 A component of a pathname exceeded 255 characters,
