52 returns the current address to which the socket
54 is bound, in the buffer pointed to by
58 argument should be initialized to indicate
59 the amount of space (in bytes) pointed to by
61 On return it contains the actual size of the socket address.
63 The returned address is truncated if the buffer provided is too small;
66 will return a value greater than was supplied to the call.
68 On success, zero is returned.
69 On error, \-1 is returned, and
77 is not a valid file descriptor.
82 argument points to memory not in a valid part of the
83 process address space.
87 is invalid (e.g., is negative).
90 Insufficient resources were available in the system
91 to perform the operation.
96 does not refer to a socket.
