Union REGS problem

[ChiGiang]

When I write a program to access registers in Visual C++. I had used :
#include <dos.h>
void main(void)
{
union REGS reg;
....
}

But the compiler don't accept REGS. How could I do that ?
Thanks very much.

To access registers, You should use CONTEXT structure (if You don't do it in a driver).
It is not so easy, and there are many differences between Windows 95/98/ME and NT/2000/XP too.
