271 * slap_response_play()

274 * - remove itself from the list, by setting op->o_callback = NULL;
275 * malloc()'ed callbacks should free themselves from inside the
276 * sc_response() function.
277 * - replace itself with another (list of) callback(s), by setting
278 * op->o_callback = a new (list of) callback(s); in this case, it
279 * is the callback's responsibility to to append existing subsequent
280 * callbacks to the end of the list that is passed to the sc_response()
282 * - modify the list of subsequent callbacks by modifying the value
283 * of the sc_next field from inside the sc_response() function; this
284 * case does not require any handling from inside slap_response_play()
286 * To stop execution of the playlist, the sc_response() function must return
287 * a value different from SLAP_SC_CONTINUE.
289 * The same applies to slap_cleanup_play(); only, there is no means to stop
290 * execution of the playlist, since all cleanup functions must be called.
