You could try using the functions:
_go32_dpmi_get_free_memory_information(*)
See - http://www.delorie.com/djgpp/doc/libc-2.00/libc_352.html#SEC352


Use the function twice. Once before you allocate anything, then once
after you allocate everything. Then, subtract the two states and
thats how much memory you have used!


Good luck,
