ARGUMENTS

  _c_c_c	    Specifies the CCC.

  _c_l_i_e_n_t__d_a_t_a
	    Specifies client data for the white	point adjustment procedure or
	    NULL.

  _c_o_l_o_r	    Specifies the new Client White Point.

  _w_h_i_t_e__a_d_j_u_s_t__p_r_o_c
	    Specifies the white	point adjustment procedure.

DESCRIPTION
  The _X_c_m_s_S_e_t_W_h_i_t_e_P_o_i_n_t	function changes the Client White Point	in the speci-
  fied CCC.  Note that the pixel member	is ignored and that the	color specif-
  ication is left unchanged upon return.  The format for the new white point
  must be _X_c_m_s_C_I_E_X_Y_Z_F_o_r_m_a_t, _X_c_m_s_C_I_E_u_v_Y_F_o_r_m_a_t, _X_c_m_s_C_I_E_x_y_Y_F_o_r_m_a_t,	or _X_c_m_s_U_n_d_e_-
  _f_i_n_e_d_F_o_r_m_a_t.	If _c_o_l_o_r is NULL, this function	sets the format	component of
  the Client White Point specification to _X_c_m_s_U_n_d_e_f_i_n_e_d_F_o_r_m_a_t, indicating
  that the Client White	Point is assumed to be the same	as the Screen White
  Point.

  The _X_c_m_s_S_e_t_W_h_i_t_e_A_d_j_u_s_t_P_r_o_c function first sets the white point adjustment
  procedure and	client data in the specified CCC with the newly	specified
  procedure and	client data and	then returns the old procedure.
