NAME
auparse_add_callback - add a callback handler for notifications
SYNOPSIS
#include <auparse.h>
void auparse_add_callback(auparse_state_t *au, auparse_callback_ptr callback,
void *user_data, user_destroy user_destroy_func);
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.
RETURN VALUE
None.
