The C++ looks messed up. I have yet to come across a keyboard that can type an arrow.
It's just a programming font ligature. If you copy and paste it you'll see the actual characters e.g. auto main() -> int { (It's also modern C++ trailing return type.)
Earlier quoted context omitted.
Driver signing is a killer issue on Windows; if you put your machine into dev/unsigned mode you get an ugly banner that can't be turned off. Much easier to design the device to avoid that. E.g. by abusing USB-HID. The desktop USB missile launcher toy is USB HID, for example.
No need to pretend to be HID. Windows has WinUSB for userspace USB drivers that don't need special signing.

int main() {Perfect timing. I'm expecting to get my hands on a MOTU MIDI Express XT from my local Guitar Center within the next couple days (I paid for it when it arrived there a couple weeks ago, but they have a mandatory waiting period on used equipment to make sure it ain't stolen), which unfortunately uses some weird proprietary protocol instead of class-compliant MIDI-over-USB — so any use over USB from my PCs (nearly all o…

Not to be too facetious but a great place for communicating with the kernel where there are a ton of other driver subsystems is... the kernel. Possibly a good addition to the article would be parallel development of an lkm. I guess it wouldn't have that windows interop but I would also be interested to see how this driver would be implemented on Windows. If it's idk 10x as many lines in the kernel vs userspace, that'…
In HFT user-space networking drivers have a long history - there is too much latency induced by switching from kernel to user space to handle networking. > OpenOnload: A user-space network stack that intercepts socket calls to bypass the kernel network stack, accelerating standard socket operations for faster networking. > Netmap: A framework providing a simple API for high-speed packet I/O in user space, bypassing m…

Why would anybody think more words more better? int main() {
template
auto multiply(A a, B b) -> decltype(a * b) {
return a * b;
}
