910 * required for every log message. They use the provided return/error
911 * value(s), if any, to construct the success/failure indication required
912 * for every log message. They only permit one "miscellaneous" token,
913 * which should contain the event-specific logging information mandated by
916 * All these calls assume the caller has previously determined that
917 * auditing is enabled by calling au_get_state().

924 * calls. Performs a basic write of an audit record (subject, additional
925 * info, success/failure). Note that this call only permits logging one
926 * caller-specified token; clients needing to log more flexibly must use
927 * the existing BSM API (au_open(), et al.) directly.
929 * Note on memory management: audit_write() guarantees that the token_t *s
