       _s is a socket descriptor.  _g_e_t_s_o_c_k_n_a_m_e returns the address
       of the socket indicated by _s.  _a_d_d_r  points  to  a  socket
       address  structure  in  which  this  address  is returned.
       _a_d_d_r_l_e_n points to an object of type ssiizzee__tt which should be
       initialized to indicate the size of the address structure.
       On return it contains  the  actual  size  of  the  address
       returned  (in  bytes).   If  _a_d_d_r does not point to enough
       space to contain the whole address of the socket, only the
       first _a_d_d_r_l_e_n bytes of the address are returned.

       If  the  call  is  successful, 0 is returned.  If the call
       fails, -1 is returned and and  error  code  is  stored  in
       eerrrrnnoo.

       _g_e_t_s_o_c_k_n_a_m_e fails if:

       [EBADF]             _s is not a valid descriptor.

       [EINVAL]            The socket has been shut down.  _s is a
                           file, not a socket.
