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.

       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.
