AUSEARCH_A...ESTAMP_ITEM(3)  Linux Audit API AUSEARCH_A...ESTAMP_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, 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 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.
