call far ptr 7:0 - обычный syscall в SysV ABI. Что ж так из-за этого нервничать-то?
What is despair? I have known it—hear my song. Despair is when you’re debugging a kernel driver and you look at a memory dump and you see that a pointer has a value of 7.

You might ask, “Why would someone write code in a grotesque language that exposes raw memory addresses? Why not use a modern language with garbage collection and functional programming and free massages after lunch?” Here’s the answer: Pointers are real. They’re what the hardware understands. Somebody has to deal with them. You can’t just place a LISP book on top of an x86 chip and hope that the hardware learns about lambda calculus by osmosis.

Similar to the Necronomicon, a C++ source code file is a wicked, obscure document that’s filled with cryptic incantations and forbidden knowledge. When it’s 3 A.M., and you’ve been debugging for 12 hours, and you encounter a virtual static friend protected volatile templated function pointer, you want to go into hibernation and awake as a werewolf and then find the people who wrote the C++ standard and bring ruin to the things that they love.
