Let's suppose that i have installed a keyboard interruption to process
keystrokes, and that i have an asm function to do something (doens't matter
what).
Now let's suppose that i am running my program and occurs a call to my
keyboard interrupt when my asm function is being executed.

Will the code in the interrupt function change the values of the registers?
Do i have to make a cli and a sti in the asm function to prevent a call to
the interrupt when the function is being executed?
Should i do a pusha and a popa in the function that the interrupt calls to
svae the register values?


Thank's Jorge Lima from Dark Angel Soft, Portugal
