Better — Ntquerywnfstatedata Ntdlldll
Working with NtQueryWnfStateData requires awareness of significant constraints:
Success is indicated by NT_SUCCESS(Status) evaluating to true (status >= 0). Common NTSTATUS values encountered when calling this function include:
return 0;
If you absolutely must work with WNF, ntdll.dll also exports Rtl* wrappers that are slightly more stable:
Monitoring changes to WNF states related to code integrity can reveal attempts to bypass security features. ntquerywnfstatedata ntdlldll better
typedef NTSTATUS (NTAPI *pNtQueryWnfStateData)( HANDLE StateName, // WNF state name (not a real handle) VOID *Buffer, // Optional type ID or scope VOID *OutputBuffer, ULONG OutputSize, ULONG *OutputNeeded );
: Receives a monotonic incrementing number that changes every time the state data is updated. Applications can store this value and later compare it to determine whether new data is available, eliminating unnecessary reads. Applications can store this value and later compare
