rtw_cbuf_empty(9)

🦋 rtw_cbuf_empty(9) — straight from the Kernel API Manual, bestie 🦋

okay so picture this: you're deep in the kernel, staring at a cbuf like 👀, and you just gotta know — is it empty or not? That's literally the whole job of rtw_cbuf_empty, no cap. She's a little helper from the rtw_cbuf family and she answers exactly one question, but she answers it flawlessly. 💅

✨ NAME ✨

rtw_cbuf_empty — test if cbuf is empty 🫙

Like, the vibe check of cbuf functions. Does it have anything in it or is it giving empty? That's it, that's the function.

---

💖 SYNOPSIS 💖

bool rtw_cbuf_empty (struct rtw_cbuf *cbuf );

one argument, one boolean return, zero drama. icon behavior fr fr ✨

---

🎀 ARGUMENTS 🎀

• cbuf — pointer of struct rtw_cbuf 🧚 the actual cbuf you're lowkey interrogating. You pass the pointer, she does the rest.

---

🌈 RETURN 🌈

returns true if cbuf is empty 💀

that's it. that's the whole return value. no secret third thing, no hidden enum, just true for "yep, empty" (and, by obvious implication, not true when it's got stuff in it). 👑

ngl, this one's a one-trick pony and that's literally her charm. don't overthink it bestie 🫶
