int 21 equivalent in C++ windows XP

Question

Interrupts are not working in inline-assembler of C++(i tried VC++ 10, GCC 4, Digital Mars). Is there any interrupt-equivalent windows free-to-access memory areas? How can i reach system properties and video ram?(can i?)

These i would like to know:

mov ah,06h
mov dl,35h 
int 21f    //would print '5' on screen but it isnt (works in only pure assembler)

and:

mov ax,1500h
mov ch,97h
int 2f   //would get me info for the cache-hit number on DI:SI

Thank you

Win32 applications don't call interrupts, they call system services. There's a number of assembly for Windows tutorials on Iczelion's page .
