int ausearch_add_timestamp_item(auparse_state_t *au, const char *op, time_t sec, unsigned milli, ausearch_rule_t how)
ausearch_add_timestamp_item adds an event time condition to the current audit search expression. The search conditions can then be used to scan logs, files, or buffers for something of interest. The op parameter specifies the desired comparison. Legal op values are <, <=, >=, > and =. The left operand of the comparison operator is the timestamp of the examined event, the right operand is specified by the sec and milli parameters.
The how value determines how this search condition will affect the existing search expression if one is already defined. The possible values are:
Returns -1 if an error occurs; otherwise, 0 for success.
Use ausearch_add_item(3) and ausearch_add_interpreted_item(3) to add conditions that check audit record fields. Use ausearch_add_expression(3) to add complex search expressions using a single function call.
