NAME

       ausearch_add_expression - build up search expression

SYNOPSIS

       #include <auparse.h>

       int ausearch_add_expression(auparse_state_t *au, const char
       *expression, char **error, ausearch_rule_t how);

DESCRIPTION

       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

       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.
