INT is an assembly language instruction for x86 processors that generates a software interrupt. It takes the interrupt number formatted as a byte value. When written in assembly language, the instruction is written like this: INT X where X is the software interrupt that should be generated (0-255). As is customary with … Se mer When generating a software interrupt, the processor calls one of the 256 functions pointed to by the interrupt address table, which is located in the first 1024 bytes of memory while in real mode (see Interrupt vector). … Se mer • INT 10H • INT 13H • DOS API • Interrupt Se mer The INT3 instruction is a one-byte-instruction defined for use by debuggers to temporarily replace an instruction in a running program in order to set a code breakpoint. … Se mer The INTO instruction is another one-byte-instruction.
