Re: Fastest way to clear a buffer

Improved version for any buffer size:

procedure ClearBuffer(pBuffer : Pointer; NumBytes : Integer)

var
NDWords : Integer;
NBytes : Integer;

begin
NDWords:=NumBytes shr 2;
NBytes:=NumBytes-NDWords;

asm
   mov  ecx, NumDWords
   mov  edi, pBuffer
   mov  eax,  0
   cld
   rep  stosd
   mov ecx, NumBytes
   rep stosb
end;

end;

(untried - feel free to criticise !)
