In brief, there isn't really a good way.
`__dpmi_get_free_memory_information' will give you some statistics, but
for a variety of reasons, they may not always reflect exactly what you can
do.  AFAIK, all you know is that you can *probably* allocate the amount
that function says is free.  The only way to know for sure is to call
`malloc' and see if it returns NULL.
