11 int getsockname(int socket, struct sockaddr *restrict address,
12 socklen_t *restrict address_len);

16 The getsockname() function shall retrieve the locally-bound name of the
17 specified socket, store this address in the sockaddr structure pointed
18 to by the address argument, and store the length of this address in the
19 object pointed to by the address_len argument.
20
21 If the actual length of the address is greater than the length of the
22 supplied sockaddr structure, the stored address shall be truncated.
23
24 If the socket has not been bound to a local name, the value stored in
25 the object pointed to by address is unspecified.
26
28 Upon successful completion, 0 shall be returned, the address argument
29 shall point to the address of the socket, and the address_len argument
30 shall point to the length of the address. Otherwise, -1 shall be
31 returned and errno set to indicate the error.
32
34 The getsockname() function shall fail if:
35
36 EBADF The socket argument is not a valid file descriptor.
37
38 ENOTSOCK
39 The socket argument does not refer to a socket.
40
41 EOPNOTSUPP
42 The operation is not supported for this socket's protocol.
43
44
45 The getsockname() function may fail if:
46
47 EINVAL The socket has been shut down.
48
49 ENOBUFS
50 Insufficient resources were available in the system to complete
