AUSEARCH_ADD_ITEM(3) Linux Audit API AUSEARCH_ADD_ITEM(3)

NAME ausearch_add_item - build up search rule

SYNOPSIS #include <auparse.h>

int ausearch_add_item(auparse_state_t *au, const char *field, const char *op, const char *value, ausearch_rule_t how);

DESCRIPTION ausearch_add_item adds one search 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 field value is the field name that the value will be checked for. The op variable describes what kind of check is to be done. Legal op values are:

exists just check that a field name exists

= locate the field name and check that the value associ- ated with it is equal to the value given in this rule.

!= locate the field name and check that the value associ- ated with it is NOT equal to the value given in this rule.

The value parameter is compared to the uninterpreted field value.

The how value determines how this search condition will affect the existing search expression if one is already defined. The possible val- ues 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.
