20 \fBsocklen_t *restrict\fR \fIaddress_len\fR);
25 The \fBgetsockname()\fR function retrieves the locally-bound name of the
26 specified socket, stores this address in the \fBsockaddr\fR structure pointed
27 to by the \fIaddress\fR argument, and stores the length of this address in the
28 object pointed to by the \fIaddress_len\fR argument.
31 If the actual length of the address is greater than the length of the supplied
32 \fBsockaddr\fR structure, the stored address will be truncated.
35 If the socket has not been bound to a local name, the value stored in the
36 object pointed to by \fIaddress\fR is unspecified.
39 Upon successful completion, 0 is returned, the \fIaddress\fR argument points to
40 the address of the socket, and the \fIaddress_len\fR argument points to the
41 length of the address. Otherwise, \(mi1 is returned and \fBerrno\fR is set to
