NAME
       getpeername - get the name of the peer socket

SYNOPSIS
       cc [ flag ... ] file ... -lxnet [ library ... ]
       #include <sys/socket.h>

       int getpeername(int socket, struct sockaddr *restrict address, socklen_t *restrict address_len);

DESCRIPTION
       The  getpeername() function retrieves the peer address of the specified socket, stores this address in the sockaddr structure pointed to by
       the address argument, and stores the length of this address in the object pointed to by the address_len argument.

       If the actual length of the address is greater than the length of the supplied sockaddr structure, the stored address will be truncated.

       If the protocol permits connections by unbound clients, and the peer is not bound, then the value  stored  in  the  object  pointed  to	by
       address is unspecified.

RETURN VALUES
       Upon successful completion, 0 is returned.  Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The getpeername() function will fail if:

       EBADF	       The socket argument is not a valid file descriptor.

       EFAULT	       The  address or	address_len parameter can not be accessed or written.

       EINVAL	       The socket has been shut down.

       ENOTCONN        The socket is not connected or otherwise has not had the peer prespecified.

       ENOTSOCK        The socket argument does not refer to a socket.

       EOPNOTSUPP      The operation is not supported for the socket protocol.

       The getpeername() function may fail if:

       ENOBUFS	       Insufficient resources were available in the system to complete the call.

       ENOSR	       There were insufficient STREAMS resources available for the operation to complete.
