Синопсис (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)
Описание (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).
Возвращаемое значение (Return value)
Returns -1 if an error occurs; otherwise, 0 for success.
