Как включить/выключить аудит?

#include <windows.h>
#include <stdio.h>
#include <ntsecapi.h>
#pragma hdrstop

// This code was kindly provided by Marc Esipovich, marc@mucom.co.il.
// The original filename was "isauditon.c".
// Modifications by felixk:
// IsAuditOn() now accepts a BOOL; if FALSE, the code will
// _not_ force the audit settings to ON.
// Changed return type to int, as it may return 0, 1, -1.
// Added a small main() to call IsAuditOn(FALSE).

/*

RETURNS: 1 if Auditing has been enabled, 0 if no action taken, -1 on error.

COMMENT: Automatically enables all audit policy events.

Values are, 0 for no log at all, 1 for success only, 2 for failure only,
3 for both success and failure.

DWORD IsAuditEnabled; // 1 = ON, 0 = OFF.
