NAME
       getpeername - get name of connected peer

SYNOPSIS
       cc [ flag ... ] file ... -lsocket  -lnsl	 [ library ... ]
       #include <sys/types.h>
       #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
       int pointed to by the namelen parameter should be initialized to	 indi‐
       cate  the amount of space pointed to by name. On return it contains the
       actual size of the name returned (in bytes), prior to  any  truncation.
       The name is truncated if the buffer provided is too small.

RETURN VALUES
       If  successful,	getpeername()  returns	0; otherwise it returns −1 and
       sets errno to indicate the error.

       The call succeeds unless:

       EBADF
		   The argument s is not a valid descriptor.

       ENOMEM
		   There was insufficient user memory  for  the	 operation  to
		   complete.

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