What happens if you try to read from a null pointer in DOS?
- pas 6y agoYou get what is at 0x0000 ?
- vngzs 6y agoI haven't actually tried this, but based on my understanding of the MS-DOS memory model it should read the contents of memory at address 0.
- hvdijk 6y agoThis is correct, and address 0 is the start address of the interrupt vector table, so there are good reasons why you might read from it.
