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 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

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