AUSEARCH_ADD_TIMESTAMP_ITEM(3)			   Linux Audit API		       AUSEARCH_ADD_TIMESTAMP_ITEM(3)

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, ause- arch_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 speci- fies the desired comparison. Legal op values are <, <=, >=, > and =. The left operand of the comparison oper- ator 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: 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.
