/VXD
This option creates a virtual device driver (VxD). When this option is specified, the default file name extension changes to .vxd. For details on VxDs, see the Microsoft Windows NT Device Driver Kit.
A .vxd file is not in Common Object File Format, and it cannot be used with DUMPBIN or EDITBIN. It does not contain debugging information. However, you can create a map file when you link a .vxd file.
A .vxd file cannot be incrementally linked.
