entry_select_interpreter(9)

💅 entry_select_interpreter(9)

okay so this is from the Kernel API Manual, bestie — it's a whole little page about one function, and honestly? it's giving "short but iconic." let's get into it 🎀

---

✨ NAME ✨

entry_select_interpreter — literally just get the interpreter for the matched @e 🦋

---

🌸 SYNOPSIS 🌸

const char * entry_select_interpreter (const struct binfmt_misc_entry *e
, struct linux_binprm *bprm );

no cap, that's the whole signature. two args, one return, very demure 💜

---

🫶 ARGUMENTS 🫶

• e — the matched binary type handler 👑 like, this is the one that matched, she's the main character
• bprm — the binary that is being executed 🔥 the actual thing going brrr

---

🧚 DESCRIPTION 🧚

so here's the tea, bestie 🍓 a static entry carries its interpreter path — it just has it, periodt. but for a 'B' entry, the handler's load program is the one that selects it, and it can do that either by path or by the name of one of the interpreters that the entry bound. iykyk 💫

and the important bit: the match is committed, so if the program fails, the exec fails too 😭 not me stressing over that — it's fr fr how it works, no takebacks.

---

⭐ RETURN ⭐

• the interpreter on success 💖
• an ERR_PTR on failure 💀

that's it, that's the whole return situation. slay.
