61 The \fBgetpeername()\fR function retrieves the peer address of the specified
62 socket, stores this address in the \fBsockaddr\fR structure pointed to by the
63 \fIaddress\fR argument, and stores the length of this address in the object
64 pointed to by the \fIaddress_len\fR argument.
67 If the actual length of the address is greater than the length of the supplied
68 \fBsockaddr\fR structure, the stored address will be truncated.
71 If the protocol permits connections by unbound clients, and the peer is not
72 bound, then the value stored in the object pointed to by \fIaddress\fR is
76 Upon successful completion, 0 is returned. Otherwise, \(mi1 is returned and
