ROM BIOS interrupts in Borland C++ 5.02

[dfound]

Hello, I am using Borland C++ 5.02 and I was trying to make ROM BIOS interrupts in a c program. But when I compile the program it says undefined structure REGS.
I tried the program in a cpp program too but with same result.
Here's my code

#include <dos.h>

#define VIDEO 0x10

void movetoxy(int x, int y)
{
	union REGS regs;

   regs.h.ah = 2;  /* set cursor position */
	regs.h.dh = y;
   regs.h.dl = x;
   regs.h.bh = 0;  /* video page 0 */
	int86(VIDEO, &regs, &regs);
}

int main(void)
{
	clrscr();
	movetoxy(35, 10);
	printf("Hello\n");
	return 0;
}

Please help me with the problem. Thanks .

I googled a bit for "union REGS" and found that all the code that uses that union
also included the <bios.h> file but I don't think you can use that bios directly from
a MS Windows environment (I might be totally wrong though).

kind regards,

Jos

JosAH is not wrong. Windows protects the bios and all access to this union is prohibited.

Yes I used the bios.h header file. I just tried a function in the help file .
The fuction was _bios_memsize() . But the compiler says call to undefined function.
My code is (this is code is exactly as is in the help file)

#include <stdio.h>
#include <bios.h>

int main(void)
{
  unsigned   memory_size;

  memory_size = _bios_memsize();   /* returns value up to 640K */

  printf("RAM size = %dK\n", memory_size);

  return 0;
}

Please tell me what is wrong

Why can't you use the Windows functions that provide this capability?

I cant see to find any functions equivalent to ROM-BIOS functions in Win32. I tried searching but of no use. It would be a great help if you give me the functions or where I can find them. Thanks

You use Windows Management Instrumentation (WMI).
