       The _i_f___f_r_e_e_n_a_m_e_i_n_d_e_x() function shall free the memory allocated by
       _i_f___n_a_m_e_i_n_d_e_x().  The _p_t_r argument shall be a pointer that was returned
       by _i_f___n_a_m_e_i_n_d_e_x().  After _i_f___f_r_e_e_n_a_m_e_i_n_d_e_x() has been called, the
       application shall not use the array of which _p_t_r is the address.
