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
       indicate the amount of space pointed to by name. On return it contains the actual size of the name returned (in bytes), prior to any  trun-
       cation. 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.

ERRORS
       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.

       ENOTCONN    The socket is not connected.

       ENOTSOCK    The argument s is not a socket.
