16 ausearch_add_item adds one search condition to the current audit search
17 expression. The search conditions can then be used to scan logs, files,
18 or buffers for something of interest. The field value is the field name
19 that the value will be checked for. The op variable describes what kind
20 of check is to be done. Legal op values are:
21
22
23 exists
24 just check that a field name exists
25
26 =
27 locate the field name and check that the value associ‐
28 ated with it is equal to the value given in this rule.
29
30 !=
31 locate the field name and check that the value associ‐
32 ated with it is NOT equal to the value given in this
33 rule.
34
35 The value parameter is compared to the uninterpreted field value.
36
37 The how value determines how this search condition will affect the
38 existing search expression if one is already defined. The possible val‐
39 ues are:
40
41 AUSEARCH_RULE_CLEAR
42 Clear the current search expression, if any, and use only
43 this search condition.
44
45 AUSEARCH_RULE_OR
46 If a search expression E is already configured, replace
47 it by (E || this_search_condition).
48
49 AUSEARCH_RULE_AND
50 If a search expression E is already configured, replace
51 it by (E && this_search_condition).
52
53
55 Returns -1 if an error occurs; otherwise, 0 for success.
