raw_atomic_l...tive_release(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

raw_atomic_long_add_negative_release β€” bestie, this is the atomic add and test if negative with release ordering one πŸ’… (yes it's a lot of words, but it's literally in the Kernel API Manual, section 9, so she's kind of a big deal πŸ‘‘)


🌸 SYNOPSIS 🌸

bool raw_atomic_long_add_negative_release (long i , atomic_long_t *v );

πŸ¦‹ ARGUMENTS πŸ¦‹

  • i β€” the long value you're adding, like the amount you're dropping into the pot πŸ“
  • v β€” pointer to the atomic_long_t, aka the thing getting updated, main character energy fr fr

πŸ’– DESCRIPTION πŸ’–

Okay so picture this: it atomically updates v to (v + i) with release ordering ✨. Atomically means nobody gets to peek at a half-finished version of the value β€” it's all or nothing, no cap πŸŽ€

Safe to use in noinstr code β€” that's the whole reason this raw_ version exists 🫢 But like, prefer atomic_long_add_negative_release elsewhere, because that's the prefect-sanctioned one and we don't do chaos for no reason πŸ’€


⭐ RETURN ⭐

true if the resulting value of v is negative, false otherwise 🌈 Simple as that, iykyk.


🧚 SEE ALSO 🧚

The vibe check: this function lives in the kernel file ./include/linux/atomic/atomic-long.h πŸ“

And now, the entire raw_atomic_long_* extended universe β€” the whole group chat, alphabetically seated, nobody left out, periodt πŸ’œ
