ausearch_add_item

AUSEARCH_ADD_ITEM(3)						  Linux Audit API					      AUSEARCH_ADD_ITEM(3)

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 val-
       ues 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.
