NAME
       ausearch_add_interpreted_item - build up search rule

SYNOPSIS
       #include <auparse.h>

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


DESCRIPTION
       ausearch_add_interpreted_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
                     associated with it is equal to the value given in this
                     rule.

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

       The value parameter is compared to the interpreted field value (the
       value that would be returned by auparse_interpret_field(3)).

       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.
