, 17:51, November 18, 2008The INT instruction x86
'''INT''' is an [[assembly language]] instruction for x86 [[central processing unit|processors]] for generating a [[software interrupt]].
It takes the interrupt number as an argument.
The interrupt number is the index into the interrupt vector table.
The interrupt vector table is a table of function pointers, each vector pointing to an interrupt.
The function pointed to by the interrupt vector table index is called upon execution of the INT XX instruction, where XX usually represents a [[hexadecimal]] value.
