Win32 API call in Delphi 3.0 DLL

I'm very new to Delphi, so forgive me if I ask a very stupid question.  
I'm trying to write a function that returns the volume ID of a floppy. When I try to compile the DLL I get the error message: 'undeclared identifier:GetVolumeInformation'. What am I doing wrong?


library MyLib;

uses
  SysUtils,
  Classes;

function GetInfo1 : LongInt ;export;
  var
     dwTemp1, dwTemp2 : LongInt;
  begin
     GetVolumeInformation (
        PChar('A:\'),
        Nil,
        0,
        @Result,
        dwTemp1,
        dwTemp2,
        Nil,
        0
        );
  end;

  exports
    GetInfo1;
end.

The problem you are having is that Delphi can't find any function (or anything else) under the name GetVolumeInfo.  If the function is in another .pas file you have to include the name of that file in your uses section.

I checked in sysutils and classes and there is no GetVolumeInfo function.  I also checked through the Delphi help and saw no reference to that function.

May I ask where you found any info on a GetVolumeInfo function?

You need to call GetVolumeInformation.
