13 socklen_t *restrict address_len);

17 The getsockname() function retrieves the locally-bound name of the
18 specified socket, stores this address in the sockaddr structure pointed
19 to by the address argument, and stores the length of this address in
20 the object pointed to by the address_len argument.
21
22
23 If the actual length of the address is greater than the length of the
24 supplied sockaddr structure, the stored address will be truncated.
25
26
27 If the socket has not been bound to a local name, the value stored in
28 the object pointed to by address is unspecified.
29
31 Upon successful completion, 0 is returned, the address argument points
32 to the address of the socket, and the address_len argument points to
33 the length of the address. Otherwise, −1 is returned and errno is set
34 to indicate the error.
35
37 The getsockname() function will fail:
38
39 EBADF The socket argument is not a valid file descriptor.
40
41
42 EFAULT The address or address_len parameter can not be
43 accessed or written.
44
45
46 ENOTSOCK The socket argument does not refer to a socket.
47
48
49 EOPNOTSUPP The operation is not supported for this socket's proto‐
50 col.

53
54 The getsockname() function may fail if:
55
56 EINVAL The socket has been shut down.
57
58
59 ENOBUFS Insufficient resources were available in the system to com‐
60 plete the call.

63 ENOSR There were insufficient STREAMS resources available for the
64 operation to complete.
