The fact that the functions have ``dpmi'' as part of their name
doesn't imply that you can only use them in DPMI mode.  When
DPMI server isn't available, go32 will provide these DPMI
services for you, so you can still use those functions.  In fact,
this is the recommended way to do it, since other ways will
probably break in v2.0, as the FAQ list explains.
