use sysopen to read/write \\.\PHYSICALDEVICExx

I need to be able to read/write to a windows device, where I only know the device as \\.\PHYSICALDEVICEx.

From my research it seems that I should use Win32API::File createfile(), but I can not find any documentation on what to do next - do I use the returned filehandle directly?
