Disarm Interrupt Information

NI-VISA allows you to specify a sequence of register operations to disarm interrupts on your device if a process terminates abnormally. (When a process terminates abnormally, it does not disarm interrupts. This leaves the system vulnerable to receiving an errant interrupt from a device that no longer has an interrupt handler, which could cause a blue screen or system hang.) NI-VISA executes the specified sequence of register operations only if the crashing process is the last process using the device.
