Console下Pause效果的函数

function PauseConsole(Prompt: PAnsiChar): boolean;
var
  hStdIn, hStdOut: THandle;
  dwRd, dwWr, i: Cardinal;

  if ((hStdIn <> 0) and (hStdOut <> 0)) then
  begin
     WriteFile(hStdOut,Prompt[0],lstrlenA(Prompt),dwWr,nil);
     while ReadConsoleInput(hStdIn,cBuf[0],128,dwRd) do
     begin

       end;
     end;
  end;
