💅 pdcs_autosearch_write — a Kernel API Manual moment

okay bestie, welcome to the pdcs_autosearch_write(9) page 💖 this one lives in the Kernel API Manual, and it's literally all about handling the autosearch flag modifying. yes, that's the whole vibe. let's get into it 🦋

---

✨ NAME ✨

pdcs_autosearch_write — this function handles autosearch flag modifying. that's it. that's the job. she's a flag-modifier and she's slaying 💅

---

🌸 SYNOPSIS 🌸

ssize_t pdcs_autosearch_write (struct kobject *kobj , struct
kobj_attribute *attr , const char *buf , size_t count );

look at her signature, so iconic, so ssize_t 🎀

---

🎀 ARGUMENTS 🎀

• kobj — the struct kobject used to share data with userspace. she's the messenger between kernel-land and user-land, no cap 🤝
• attr — the kobject attributes. the ✨attributes✨ of the kobject, periodt.
• buf — the input buffer to read from. this is where the tea comes in 🍓
• count — the number of bytes to be read. how much of the tea, exactly, in bytes 🔥

---

🦋 DESCRIPTION 🦋

so we will call this function to change the current boot flags. that's the whole point, bestie — boot flags getting a lil makeover 🌈

and we expect a precise syntax:

...and that's genuinely where the page ends 💀 like, the manpage says "we expect a precise syntax:" and then literally nothing follows. the syntax is giving mystery, giving main character energy, giving not shown here 🙈 i'm not gonna make one up for you because that would be lying and we don't do that here. if you need the actual syntax, go look at the kernel file, iykyk 🧚

fr fr though: this page does not spell out the syntax. that's not me skipping it, that's genuinely the whole page. don't come for me 😭
