int auparse_normalize_key(auparse_state_t *au);

After calling the auparse_normalize function, you will probably want to access the audit event data. These function provide access to the results of the normalization. There are 2 kinds of function, metadata and positioning.

The metadata functions all return a pointer to a string that describes something about the event. This data does not live inside the event but is kept in lookup tables inside the auparse library.

The positioning function are different in that they move the internal cursor of auparse to the record and field that contains the information you want. You then use field accessor functions to retrieve the values.

The positioning functions return < 0 on error, 0 if uninitialized, and 1 on success. The metadata functions return NULL on error and a pointer to a string on success.

auparse_normalize(3), auparse_get_field_str(3), auparse_interpret_field(3).
