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. If
36 you are trying to match against a field who's type is
37 AUPARSE_TYPE_ESCAPED, you will want to use the ausearch_add_inter‐
38 preted_item() function instead.
39
40 The how value determines how this search condition will affect the
41 existing search expression if one is already defined. The possible val‐
42 ues are:
43
44 AUSEARCH_RULE_CLEAR
45 Clear the current search expression, if any, and use only
46 this search condition.
47
48 AUSEARCH_RULE_OR
49 If a search expression E is already configured, replace
50 it by (E || this_search_condition).
51
52 AUSEARCH_RULE_AND
53 If a search expression E is already configured, replace
54 it by (E && this_search_condition).
55
56
58 Returns -1 if an error occurs; otherwise, 0 for success.
