How can I estimate amount of free / busy memory
in the program runing under PMODSTUB DPMI server.
For example _go32_dpmi_remaining_physical_memory() and
go32_dpmi_remaining_virtual_memory() return values that have no 
sense (4294967295 and 67107840).
-------- __dpmi_free_mem_info information ---------
largest_available_free_block_in_bytes = 67107840
maximum_unlocked_page_allocation_in_pages = 16383
maximum_locked_page_allocation_in_pages = 16383
linear_address_space_size_in_pages = 4294967295
total_number_of_unlocked_pages = 4294967295
total_number_of_free_pages = 4294967295
total_number_of_physical_pages = 4294967295
free_linear_address_space_in_pages = 4294967295
size_of_paging_file_partition_in_pages = 4294967295
-------- __dpmi_memory_info information ---------
total_allocated_bytes_of_physical_memory_host = 1573856
total_allocated_bytes_of_virtual_memory_host = 426244
total_available_bytes_of_virtual_memory_host = 65540
total_allocated_bytes_of_virtual_memory_vcpu = 426208
total_available_bytes_of_virtual_memory_vcpu = 426172
total_allocated_bytes_of_virtual_memory_client = 33
total_available_bytes_of_virtual_memory_client = 984
total_locked_bytes_of_memory_client = 0
max_locked_bytes_of_memory_client = 393984
highest_linear_address_available_to_client = 66585560
size_in_bytes_of_largest_free_memory_block = 65536992
size_of_minimum_allocation_unit_in_bytes = 90641
size_of_allocation_alignment_unit_in_bytes = 1008
  
on computer with 128 MB.

I'd like to trace my program which uses STL and sometimes dies
with "out of memory" message though my estimations show than 
only 30-50% of memory is allocated at the moment.

Thanks in advance,

Michael
