I don't get it - is there any particular reason why you need to use
__dpmi_allocate_memory() instead of malloc()?  From your post you don't
seem to realize that under DPMI it doesn't matter where any given chunk
of allocated memory comes from unless you need it for some specific
purpose (like installing real-mode interrupt handlers or something).
All available memory (DOS, high, EMS, XMS, and virtual) is all combined
into one large pool that malloc() and related functions draw from.

If you really want to know how to use __dpmi_allocate_memory(), read
the DPMI Overview in the libc reference of the DJGPP docs for the
__dpmi_meminfo structure, which is what is created by the above
function.
