Honestly, i have no idea what
COM or
COM+ or
DCOM has to do here in this thread, but for the sake of clarification
This should be a Bonus Information, to keep in mind, that Microsoft Windows used "self references" its function references.
Don't make you hard on this. I don't can expect that you can understand all these things of Computers and the differences between the Calling Convention, ABI, and Operating interna of each one. Because all
OS have it's own kernel behavior.
And yes, you can do INT'errupt on 32/64-Bit machines, but then, you have to switch from the 32/64-bit protected-mode into the 16-bit real-mode of the CPU. But doing this, you have to "store" all registers, before you switch, and after you switch back into 64-bit CPU mode, you have to "re-store" all registers to avoid crash or prompts of MAV's.
