πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸŽ€ _clkdm_register(9) β€” like, the kernel API manual era πŸŽ€

okay bestie, so this is a page from the Kernel API Manual, section 9, and it's all about _clkdm_register. Yes it starts with an underscore. Yes that's on purpose. Come with me πŸ’…


✨ NAME ✨

_clkdm_register β€” register a clockdomain πŸ•πŸ‘‘

✨ SYNOPSIS ✨

int _clkdm_register (struct clockdomain *clkdm );

πŸ’– ARGUMENTS πŸ’–

  • clkdm β€” literally a struct clockdomain *, bestie. That's the one you're registering. That's the whole vibe. 🫢

🌸 DESCRIPTION 🌸

So what this icon does is it adds a clockdomain to the internal clockdomain list. That's it, that's the job, and honestly? It ate. πŸ”₯

But listen, the return value is where the plot twists happen:

  • Returns -EINVAL if you hand it a null pointer. Do not do that. πŸ™ˆ
  • Returns -EEXIST if a clockdomain is already registered by the name you provided. Somebody got there first, and it was not you. 😭
  • Returns 0 upon success. Slay. 0 is the good number. 🌈⭐
no cap: -EINVAL and -EEXIST are the two failure modes, and 0 means you did it. memorize that and you're golden πŸ’œ
