about HalGetInterruptVector's parameter

NTDEV

Hi all,

Even though I know HalGetInterruptVector is a obsolete function, I still
want to know how to use this function.

ULONG
HalGetInterruptVector(
IN INTERFACE_TYPE InterfaceType,
IN ULONG BusNumber,
IN ULONG BusInterruptLevel,
IN ULONG BusInterruptVector,
OUT PKIRQL Irql,
OUT PKAFFINITY Affinity
);

I’m confused about the BusInterruptLevel and BusInterruptVector. In my
opinion, I think BusInterruptVector is irq number(the pin number of 8259a).
It that right? And what about BusInterruptVector?
HalGetInterruptVector will return a number, which is IDT item number? Please
correct it if I make a mistake.

by convention they are both the same values, but you seriously do not
want to be using this function.
