Actually, dpmi_get_free_memory will give you almost no useful
information about the memory really in use by your program. You may
notice that you have a major leak if it keeps decreasing all the time
(i.e. your program grows without bounds), but that's not always a
precise diagnosis (heap fragmentation can lead to similar behaviour).

I suggest you try a malloc() checker like 'CSS' (sp?) or Nate
Eldredge's neat YAMD. Among other misuses of allocated storage,
they'll point out any memory leaked by your program.
