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.
