mei_ext_next(9)

💅 mei_ext_next — a Kernel API Manual moment

ok so this is mei_ext_next from the kernel API manual, bestie, and it's genuinely one of the cutest little helper functions ever — it's literally just "hey, what's the next extended header on the TLV list?" 🎀

✨ NAME ✨

mei_ext_next — following extended header on the TLV list 🦋

✨ SYNOPSIS ✨

struct mei_ext_hdr * mei_ext_next (struct mei_ext_hdr *ext );

✨ ARGUMENTS ✨

• ext — the current extend header, like, the one you're standing on right now 👑 (yes it's spelled "extend" in the original, we don't fix it, we respect it)

✨ CONTEXT ✨

ok this is the part where you gotta pay attention bestie, no scrolling past 🙈

fr fr — this function does not check for overflows. one should call mei_ext_last before. that's the whole vibe check. do that first.

✨ RETURN ✨

the following extend header after ext ✨ that's it, that's the whole gift 🎁
