Hi guys,
I'm trying to convert a C++ FOR loop to Delphi, but I have no idea how to do it...

this is the C++ function:

bool bCompare(const BYTE* pData, const BYTE* bMask, const char* szMask)
{
    for(;*szMask;++szMask,++pData,++bMask)
        if(*szMask=='x' && *pData!=*bMask)   return 0;
    return (*szMask) == NULL;
}

Open in new window


I just got convert the function declaration:

function bCOmpare( pData: PBYTE; bMask: PBYTE; szMask: PCHAR):boolean;
begin
//...
end;

Open in new window


How is the conversion?

Thanks

here it is:

function bCompare(pData: PBYTE; bMask: PBYTE; szMask: PChar): Boolean;
begin
  while (szMask^ <> #0) do
  begin
    if (szMask^ = 'x') and (pData^ <> bMask^) then
    begin
      Result := False;
      Exit;
    end;
    Inc(pData);
    Inc(bMask);
    Inc(szMask);
  end;

  Result := (szMask^ = #0);
end;

Open in new window
