AUSEARCH_ADD_TIMESTAMP_ITEM_EX(3)

NAME
ausearch_add_timestamp_item_ex - build up search rule

SYNOPSIS
#include <auparse.h>

int ausearch_add_timestamp_item_ex(auparse_state_t *au, const char *op, time_t sec, unsigned milli, unsigned serial, 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, milli, and serial parameters.

The how value determines how this search condition will affect the existing search expression if one is already defined. The possible values 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_expression(3) to add complex search expressions using a single function call.
