#c programming

There's a quirk in C where the cases of a switch statement can be wrapped in another control construct. A few years ago, I remember seeing an example of a piece of code that took advantage of this by wrapping the cases in a do-while loop as a way of (partially) unrolling the loop, but I'd forgotten what it was called, and couldn't seem to find it anywhere, despite searching many times.

It's called Duff's Device, and it's evil, and hideous, and brilliant, and I love it, and I'm so glad that I finally found it again.

working with memory in low level programming beyond malloc and free is so funny

like, what do you mean the OS actually reserves 4kb on an alloc and gives me the size I want, instead of only reserving the 16 bytes I ordered?

and what was that? I need to ALIGN my pointers in a arena? THEY'RE ALREADY ALIGNED IN 8 BITS BRO, THATS THE WHOLE REASON WE INVENTED THE BYTE

oh you gotta be kidding me. I need a header for every allocation in a stack allocator? at least is something small right?... 8 BYTES???? FOR EACH ALLOCATION???? IN THIS ECONOMY????
