param_get_dyndbg_classes(9)

💅 param_get_dyndbg_classes(9) — from the Kernel API Manual, bestie

okay so picture this: it's a whole kernel API manual page, and it's here to tell you about a classes reader. yes, a reader. of classes. keep up 🫶

---

✨ NAME ✨

param_get_dyndbg_classes — the classes reader, periodt. she reads. that's her job. 👑

---

🌸 SYNOPSIS 🌸

int param_get_dyndbg_classes (char *buffer , const struct kernel_param *kp );

look at her go, literally two arguments and a dream 💖

---

🎀 ARGUMENTS 🎀

• buffer — a string description of the controlled bits, which then becomes -> classes. it's giving "words in, classes out" energy ✨
• kp — okay so kp->arg has state: the bits, and the map. that's it, that's the whole vibe 🔥

---

🦋 DESCRIPTION 🦋

so what does she actually do? she reads the last written state — but heads up bestie, the underlying prdbg state may have been altered by direct >control. like, someone else touched it. rude, but okay 🙈

and the display formatting? iconic:

• 0x for DISJOINT
• 0-N for LEVEL

Returns: #chars written or <0 on error — so if you get a negative back, that's your sign something went off, ngl 💀
