That's the case with any malloc. When you try to exceed the amount of memory
you have, it does return NULL.

malloc uses DPMI functions to allocate memory.

There's no need to get into the DPMI functions at all. All you need to do is
to malloc the amount of space you need (there's no 640K or 1M limit when
you're working on DJGPP ;-)) and then grab the data into it.
