need of intrupt table under c????

well ,
i m trying to start a bit of hardware intraction using c ,one of my friend suggested me to get to knowledge of interrupt vector table for x86 family of processors...................
can any one tell me how to generate a software interupt in c and list me out with all 256 interupts(TABLE) or a lol(LIST OF LINKs) .

Try these links

math girl these links dont have list of 256 intrupts.......... but thanks a lot they got a cream information over them
if any one familear with intrupts please-please help me :confused:

Ralf Brown's Interrupt List This is one of the best lists on the internet. It can also be found on a page from the first list I gave you.

Have you been googling? It might help if you spell it as interrupt instead of interupt.

You might want to learn some hex, too. Knowing some of the things that are possible from what you are asking...and after seeing your interests in your profile ("cracking,hacking,reverse engeniearing "), I'm not sure (could be wrong, though) your intentions are quite in line with the security focus of this board.

well that a new thing.
what are these interrupts?
for wat they are used ? :confused:
link provided is bit confusing (soory for that mathgirl).

Cut and paste.
open a DOS window, Type debug<filename, it will assemble a com file, executable in DOS
In the source code, all the "int" instructions are interrupts. They give access to OS
or BIOS services in DOS programming. In C, you would probably have to write
a function in assembly language and call it from C, or maybe your compiler permits
assembly code inline in the C source file.
:cool:
