  35. DESCRIPTION
  36.      Tk_OwnSelection arranges for _t_k_w_i_n to become the  new  owner
  37.      of the primary selection.  After this call completes, future
  38.      requests for the selection  will  be  directed  to  handlers
  39.      created  for  _t_k_w_i_n  using  Tk_CreateSelHandler.  When _t_k_w_i_n
  40.      eventually loses  the  selection  ownership,  _p_r_o_c  will  be
  41.      invoked  so  that  the  window  can clean itself up (e.g. by
  42.      unhighlighting the selection).  _P_r_o_c should  have  arguments
  43.      and result that match the type Tk_LostSelProc:
  44.           typedef void Tk_LostSelProc(ClientData _c_l_i_e_n_t_D_a_t_a);
  45.      The _c_l_i_e_n_t_D_a_t_a parameter to _p_r_o_c is a copy of the _c_l_i_e_n_t_D_a_t_a
  46.      argument  given to Tk_OwnSelection, and is usually a pointer
  47.      to a data structure containing application-specific informa-
  48.      tion about _t_k_w_i_n.
  49.  
  50.      Once a window has become selection  owner,  it  will  remain
  51.      owner until either the window is deleted or until some other
  52.      window claims ownership.  There is no way for  a  window  to
  53.      disavow ownership of the selection once it has received it.
