NAME         top

       ausearch_add_expression - build up search expression

SYNOPSIS         top

       #include <auparse.h>
       int ausearch_add_expression(auparse_state_t *au, const char
       *expression, char **error, ausearch_rule_t how);

DESCRIPTION         top

       ausearch_add_item adds an expression to the current audit search
       expression.  The search conditions can then be used to scan logs,
       files, or buffers for something of interest.  The expression
       parameter contains an expression, as specified in
       ausearch-expression(5).
       The how parameter determines how this search expression 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 expression.
              AUSEARCH_RULE_OR
                     If a search expression E is already configured, replace
                     it by (E || this_search_expression).
              AUSEARCH_RULE_AND
                     If a search expression E is already configured, replace
                     it by (E && this_search_expression).

RETURN VALUE         top

       If successful, ausearch_add_expression returns 0.  Otherwise, it
       returns -1, sets errno and it may set *error to an error message; the
       caller must free the error message using free(3).  If an error
       message is not available or can not be allocated, *error is set to
       NULL.
