You can try with FillMemory_() (RtlZeroMemory_() is not supported in Windows 9X/Me).

Code: Select all

; The FillMemory macro fills a block of memory with a specified value.
; 
; void FillMemory(
;   PVOID Destination,
;   SIZE_T Length,
;   BYTE Fill
; );
FillMemory_(*Buffer, BufferSize, FillValue) ; <-- Only lower byte is used

But, since they're both Windows macros, maybe it doesn't work either (can't test right now). You can use this as a replacement:

Code: Select all

For i=*Buffer To *Buffer+BufferSize
  PokeB(i, FillValue.b)
Next i

Or this:

Code: Select all

  push edi
  lea edi, *Buffer ; Memory address to fill
  mov ecx, BufferSize
  shr ecx, 2
  mov al, FillValue ; FillValue.b !!!
  rep stosb
  pop edi

If your memory size is dword or qword aligned, you can do it faster. I think this should work. Regards,
