GETPEERNAME(2)		   Linux Programmer's Manual		GETPEERNAME(2)

NAME
       getpeername - get name of connected peer	socket

SYNOPSIS
       #include	<sys/socket.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 system  to  perform
	      the operation.

       EFAULT The  name	 parameter points to memory not	in a valid part	of the
	      process address space.

CONFORMING TO
       SVr4, 4.4BSD (the getpeername function call first appeared in  4.2BSD).

NOTE
       The third argument of getpeername is in reality an `int *' (and this is
       what BSD	4.* and	libc4 and libc5	have).	Some POSIX confusion  resulted
       in the present socklen_t.  The draft standard has not been adopted yet,
       but glibc2  already  follows  it	 and  also  has	 socklen_t.  See  also
       accept(2).
