ausearch_add_expression

AUSEARCH_ADD_expression(3)					  Linux Audit API					AUSEARCH_ADD_expression(3)

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  possi-
       ble 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.

SEE ALSO
