Имя (Name)

auparse_add_callback - add a callback handler for notifications


Синопсис (Synopsis)

#include <auparse.h>

void auparse_add_callback(auparse_state_t *au, auparse_callback_ptr callback, void *user_data, user_destroy user_destroy_func);


Описание (Description)

auparse_add_callback adds a callback function to the parse state which is invoked to notify the application of parsing events. This is part of the event feed API.

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.
