tcw_finalize(9)

🎀 tcw_finalize(9) 🎀

okay so like, welcome to the Kernel API Manual, bestie 💅 this little page is all about tcw_finalize, and honestly? she's the finisher. the closer. the one who ties the bow 🎀 at the end of your tcw setup. let's get into it.

---

✨ NAME ✨

tcw_finalize — finalize tcw length fields and tidaw list 🦋

---

✨ SYNOPSIS ✨

void tcw_finalize (struct tcw *tcw , int num_tidaws );

---

✨ ARGUMENTS ✨

• tcw — pointer to the tcw 👑 like, that's the main character right there, give her a pointer
• num_tidaws — the number of tidaws used to address input/output data, or zero if no tida is used 🍓 (yes, zero, she's allowed to be nothing, no judgment)

---

✨ DESCRIPTION ✨

so here's the vibe check 💖 she calculates the input-/output-count and the tccbl field in the tcw, adds a tcat to the tccb, and terminates the data tidaw list if used. that's it, that's the whole glow-up ✨

---

✨ NOTE ✨

🫶 real talk, important stuff: in case input- or output-tida is used, the tidaw-list must be stored in contiguous storage (no ttic). also the tcal field in the tccb must be up-to-date. no cap, don't skip this one 🙈
