STUB
When used in a module definition file that builds a virtual device driver (VxD), allows you to specify a file name that contains an IMAGE_DOS_HEADER structure (defined in WINNT.H) to be used in the virtual device driver (VxD), rather than the default header.
STUB:filename
Remarks
An equivalent way to specify filename is with the /STUB linker option.
STUB is valid in a module definition file only when building a VxD.
