The documentation of this function explains that this service requires
DPMI v1.0 extensions. CWSDPMI supports it, but most of the other DPMI
servers, including the one built into Windows, do not.
So, unless you run your program in plain DOS, or use 386Max as your DPMI
server, you cannot use this function.
Try reading section 18.7 of the FAQ, it might suggest an alternative
approach.
