✨ libnvme_sed_l0_next(9) ✨

okay so this one lives in the libnvme API manual and it's literally the cutest little iterator ever β€” it's called libnvme_sed_l0_next and it hands you the next Level 0 Discovery descriptor like it's passing you fries 🍟 bestie, let's go.


🌸 NAME 🌸

libnvme_sed_l0_next β€” bestie, it returns the next Level 0 Discovery descriptor πŸ’… no cap, that's the whole job.


πŸ¦‹ SYNOPSIS πŸ¦‹

struct tcg_l0_desc * libnvme_sed_l0_next (void *buf , size_t len ,
       struct tcg_l0_desc *desc );

like, look at her. icon behavior. πŸŽ€


πŸ’œ ARGUMENTS πŸ’œ

  • buf β€” the Level 0 Discovery data, aka the vibe source 🫢
  • len β€” the size of buf, in bytes (yes, bytes, we count in bytes here)
  • desc β€” the current descriptor, or NULL to get the first descriptor πŸ‘‘ (pass NULL to start, that's your main character entry point)

🌈 DESCRIPTION 🌈

So the way this works: the walk ends at the length reported in the header, or at the end of buf β€” whichever comes first, fr fr. 🏁

And listen, this part matters: a descriptor which does not fit completely ends the walk. Like, if it doesn't fit, we're done, no partials, no half-descriptors, periodt. πŸ’€


⭐ RETURN ⭐

A pointer to the next descriptor πŸ’– … or NULL if there is none 😭 (that's your "you've reached the end, log off" signal).


ngl, always check that return value, bestie β€” NULL is the polite way of saying "no more for you" πŸ™ˆ
