find_any_unique_sec(9)

💅 find_any_unique_sec(9) — like, the Kernel API Manual page, bestie 🎀

okay so picture this: you're deep in Kernel API Manual territory and this little function, find_any_unique_sec, is the main character. Her whole job? Find a unique section index by name. That's it. That's the vibe. ✨

🌸 NAME 🌸

find_any_unique_sec — find a unique section index by name, periodt 💅

---

🦋 SYNOPSIS 🦋

int find_any_unique_sec (const struct load_info *info , const char *name );

---

🍓 ARGUMENTS 🍓

• info — the load info for the module we're scanning, iykyk 👀
• name — the name of the section we're looking for, like literally the string we're hunting for 🔍

---

💖 DESCRIPTION 💖

So what does she do? She locates a unique section by name. That's the whole assignment, and she ate. 💅

Also important: she ignores SHF_ALLOC. Not me stressing about flags — she simply doesn't care, no cap 🙈

---

⭐ RETURN ⭐

Here's the vibe check on what you get back:

• the section index if it was found uniquely 👑
• zero if it's absent entirely 😭
• a negative count of total instances if multiple were found — like, "girl there's more than one" energy 💀
