NAME
       getpeername - get name of connected peer

SYNOPSIS
       #include <network.h>

       int  getpeername(int  s,  struct sockaddr *name, socklen_t
       *namelen);

DESCRIPTION
       Getpeername returns the name  of  the  peer  connected  to
       socket  s.  The namelen parameter should be initialized to
       indicate the amount of  space  pointed  to  by  name.   On
       return  it  contains  the actual size of the name returned
       (in bytes).  The name is truncated if the buffer  provided
       is too small.

RETURN VALUE
       On  success,  zero is returned.  On error, -1 is returned,
       and errno is set appropriately.

ERRORS
       EBADF   The argument s is not a valid descriptor.

       ENOTSOCK
               The argument s is a file, not a socket.

       ENOTCONN
               The socket is not connected.

       ENOBUFS Insufficient resources were available in the  sys-
               tem to perform the operation.
