.SH NAME 
socket_info \- retrieving IP connection information for an existing socket
.SH SYNTAX
.B #include \(dqsocket_if.h\(dq

int \fBsocket_local\fP(int \fIs\fR,char \fIip\fR[16],
                uint16 *\fIport\fR,uint32 *\fIscope_id\fR);

int \fBsocket_remote\fP(int \fIs\fR,char \fIip\fR[16],
                uint16 *\fIport\fR,uint32 *\fIscope_id\fR);
.SH DESCRIPTION
.B socket_local 
returns the local IPv6 or IPv4-mapped IPv6 address as \fIip\fR, 
port as \fIport\fR and perhaps the scope_id as \fIscope_id\fR for the UDP or TCP socket.

.B socket_remote
returns the remote IPv6 or IPv4-mapped IPv6 address as \fIip\fR, 
port as \fIport\fR and perhaps the scope_id as \fIscope_id\fR for the UDP or TCP socket.

.SH "RETURN CODES"
If something goes wrong, 
.B socket_local 
and
.B socket_remote
return
.IR -1 , 
setting 
.I errno
appropriately.
.SH EXAMPLE
#include <socket_if.h>
  int \fIs\fR;
  char \fIip\fR[16];
  uint16 \fIport\fR;

  if (socket_remote(s,ip,&port,0) == -1)
    err_tmp("",111,"unable to get remote address: ");
