GETPEERNAME(3P)		   POSIX Programmer's Manual	       GETPEERNAME(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       getpeername - get the name of the peer socket

SYNOPSIS
       #include <sys/socket.h>

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

DESCRIPTION
       The getpeername() function shall retrieve the peer address of the spec‐
       ified  socket,  store this address in the sockaddr structure pointed to
       by the address argument, and store 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 shall 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 VALUE
       Upon successful completion, 0 shall be returned. Otherwise, -1 shall be
       returned and errno set to indicate the error.

ERRORS
       The getpeername() function shall fail if:

       EBADF  The socket argument is not a valid file descriptor.

       EINVAL The socket has been shut down.

       ENOTCONN
	      The  socket  is  not connected or otherwise has not had the peer
	      pre-specified.

       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.
