Using: DJGPP V2.0

Hi djgpp gurus !

I have a little problem when I want to detect available memory with
djgpp V2. (I think this is about the same with v1.12m4).

Here is a little program that demonstrate the problem. The values returned
by the prog are quite strange. look by yourself.

Are there ather ways to get available memory ?

Thanks.

-- Sample program memory.cc ----------

#include <stdlib.h>
#include <dpmi.h>
#include <stdio.h>

void PrintFreeMem(void)
{ printf("Free Physical memory : %uld bytes\n",_go32_dpmi_remaining_physical_memory());
  printf("Free Virtual  memory : %uld bytes\n",_go32_dpmi_remaining_virtual_memory());
}

int main()
{ printf("MEMORY free test - DJGPP compiler\n");
  PrintFreeMem();
  printf("\nAllocation 34658 bytes...\n\n");
  char *Dummy=(char*)malloc(34658);
  PrintFreeMem();
  printf("\nFreeing the memory allocated\n\n");
  free(Dummy);
  PrintFreeMem();
  printf("\nDone.\n");
  return 0;
}
