QB_RB_CHMOD(3)

💖 QB_RB_CHMOD — like chmod but make it ringbuffer 💖

okay so bestie, welcome to the libqb Programmer's Manual, page qb_rb_chmod(3). this is the lil function that's basically chmod but for your ringbuffer's resources. yes, THE ringbuffer. the one you're emotionally attached to. she's getting a permission glow-up ✨

---

🎀 NAME 🎀

qb_rb_chmod — Like chmod, it changes the mode of the ringbuffer's resources.

like. exactly that. no notes. she does what it says on the tin 💅

---

🌸 SYNOPSIS 🌸

#include <qb/qbrb.h>

int32_t qb_rb_chmod(
    qb_ringbuffer_t   *rb,    /* ringbuffer instance */
    mode_t             mode   /* mode to change to */
);

so you're pulling in <qb/qbrb.h>, and then you hand her two things: the ringbuffer, and the mode you want. that's it. that's the whole vibe 🦋

---

🫶 PARAMS 🫶

• rb — ringbuffer instance. the actual ringbuffer you're about to mess with, your main character 🫶
• mode — mode to change to. the new perms. the fit. the look. the aesthetic she's switching into 👑

---

🌈 DESCRIPTION 🌈

okay so... not me opening the description section and there's literally nothing here 😭 the original manpage just leaves it blank. empty. a void. no explanation, no lore, no backstory. she simply does not elaborate 💀

so we're all just gonna have to live with the mystery. iconic behaviour honestly.

---

⭐ RETURN VALUE ⭐

• 0 — == ok. we love a zero. we celebrate a zero. she ate and left no crumbs 🎉
• -errno — for error. something went wrong, and she's telling you which wrong via the negative errno. rude but informative 💀

bestie heads up: that DESCRIPTION section being empty is straight from the source, fr fr. i'm not hiding anything from you, the manpage just didn't write one. don't come for me 🥺
