calipso_doi_getdef(9)

💅 calipso_doi_getdef — a whole Kernel API Manual moment ✨

okay bestie, so this one lives in the Kernel API Manual, section 9, and it's called calipso_doi_getdef. ngl it's a lil lookup function and it's lowkey iconic for it 🎀

---

🌸 NAME 🌸

calipso_doi_getdef — literally returns a reference to a valid DOI definition. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

struct calipso_doi * calipso_doi_getdef (u32 doi );

like… that's the whole signature. copy it exact, don't come for me 🫶

---

🦋 ARGUMENTS 🦋

• doi — the DOI value 👀 that's the one thing you hand over.

---

💅 DESCRIPTION 💅

so here's the tea ☕: it searches for a valid DOI definition, and if one is found, it gets returned to the caller. slay. if not? you get NULL. no cap, that's the whole deal 😭

⚠️ important, bestie: the caller must make sure that calipso_doi_putdef is called when the caller is done. the way that's not optional — it's giving "don't forget to clean up or the kernel will side-eye you" energy 💀
