NAME ausearch_add_timestamp_item - build up search rule

SYNOPSIS #include <auparse.h>

int ausearch_add_timestamp_item(auparse_state_t *au, const char *op, time_t sec, unsigned milli, ausearch_rule_t how)

DESCRIPTION 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 val- ues are:

AUSEARCH_RULE_CLEAR Clear the current search expression, if any, and use only this search condition.

AUSEARCH_RULE_OR If a search expression E is already configured, replace it by (E || this_search_condition).

AUSEARCH_RULE_AND If a search expression E is already configured, replace it by (E && this_search_condition).

RETURN VALUE Returns -1 if an error occurs; otherwise, 0 for success.

APPLICATION USAGE Use ausearch_add_item(3) and ausearch_add_interpreted_item(3) to add conditions that check audit record fields. Use ausearch_add_expres- sion(3) to add complex search expressions using a single function call.
