NAME         top

       ausearch_add_item - build up search rule

SYNOPSIS         top

       #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         top

       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
                     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 uninterpreted field value.
       If you are trying to match against a field who's type is
       AUPARSE_TYPE_ESCAPED, you will want to use the
       ausearch_add_interpreted_item() function instead.

       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         top

       Returns -1 if an error occurs; otherwise, 0 for success.
