itcw_finalize(9)

✨ NAME ✨

okay so bestie, welcome to the itcw_finalize(9) page from the Kernel API Manual 🎀 — this one is literally here to calculate length and count fields of the itcw.

🌸 SYNOPSIS 🌸

void itcw_finalize (struct itcw *itcw );

💅 ARGUMENTS 💅

• itcw — address of the itcw. that’s the whole argument, and she’s simple, iconic, and to the point 🫶

🦋 DESCRIPTION 🦋

okay so what’s the main character task? it calculates the tcw input-/output-count and tccbl fields, and adds a tcat the tccb ✨

if input- or output-tida is used, the tidaw-list must be stored in continuous storage (no ttic) — like, non-negotiable, bestie 😭

⚠️ also the tcal field in the tccb must be up-to-date. do not show up with a stale tcal, that’s giving broken vibes 💀
