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.
