The signature of the callback is: void auparse_callback(auparse_state_t *au, auparse_cb_event_t cb_event_type, void *user_data); When the callback is invoked it is passed: au a pointer to the parse_state cb_event_type enumerated value indicating the reason why the callback was invoked user_data pointer to user supplied private data. May be NULL. user_destroy_func pointer to function called when user_data is destroyed. May be NULL. The signature is: void destroy(void *user_data); The destroy() function should be prepared to accept user_data possibly being NULL. The cb_event_type argument indicates why the callback was invoked. It's possible values are: AUPARSE_CB_EVENT_READY A complete event has been parsed and is ready to be examined. This is logically equivalent to the parse state immediately following auparse_next_event() See auparse_feed(3) for a complete code example.RETURN VALUEReturns the previous callback pointer.SEE ALSOauparse_feed(3), auparse_flush_feed(3).AUTHORJohn Dennis Red Hat May 2007 AUPARSE_ADD_CALLBACK(3)
