    Hi, I am trying to use DeviceIoControl() to get a drive length into the GET_LENGTH_INFORMATION structure. When I compile, I get an error stating "GET_LENGTH_INFORMATION: undeclared identifier" I have included 'WinIOCtl.h' as specified in the MSDN docs. I am also running XP. The code used is simply; GET_LENGTH_INFORMATION len; Does anyone know why I should be getting these errors?? Thanks

      But did you miss this in the winioctl.h file:

      #if(_WIN32_WINNT >= 0x500)

        Requirements

        Client Requires Windows Vista or Windows XP. Server Requires Windows Server 2008 or Windows Server 2003. you likely have to declare a WINVER[^] and/or others as well.
