21 * Create a newly allocated log4j logging event rule.

31 * Set the name pattern of a log4j logging event rule.
33 * Pattern can contain wildcard '*'. See man lttng-enable-event.
35 * Return LTTNG_EVENT_RULE_STATUS_OK on success, LTTNG_EVENT_RULE_STATUS_INVALID
36 * if invalid parameters are passed.

44 * The caller does not assume the ownership of the returned pattern. The
45 * pattern shall only only be used for the duration of the event rule's
46 * lifetime, or before a different pattern is set.
48 * Returns LTTNG_EVENT_RULE_STATUS_OK and a pointer to the event rule's pattern
49 * on success, LTTNG_EVENT_RULE_STATUS_INVALID if an invalid
50 * parameter is passed, or LTTNG_EVENT_RULE_STATUS_UNSET if a pattern
