💖 sw842_decompress(9) — Kernel API Manual 💖

Welcome to the Kernel API Manual page for sw842_decompress(9), bestie. Buckle up, we're decompressing ✨

✨ NAME ✨

sw842_decompress — the description slot is literally blank in the source, so that's the whole name entry, periodt 🙈

🌸 SYNOPSIS 🌸

int sw842_decompress (const u8 *in , unsigned int ilen , u8 *out ,
       unsigned int *olen );

🎀 ARGUMENTS 🎀

Okay so the manpage did not describe these at all. Every single one is officially listed as -- undescribed --, and I am not gonna invent lore. Respect the source, bestie 💅

  • in — -- undescribed -- 😭
  • ilen — -- undescribed -- 😭
  • out — -- undescribed -- 😭
  • olen — -- undescribed -- 😭

💅 DESCRIPTION 💅

Okay so here's the actual vibe: decompress the 842-compressed buffer of length ilen at in to the output buffer out, using no more than olen bytes. That's the assignment, and it ate 🔥

The compressed buffer must be only a single 842-compressed buffer, with the standard format described in the comments in 842.h. Not a little buffer pile, not a buffer stack — one single 842-compressed buffer. Slay 💖

Processing will stop when the 842 "END" template is detected, not the end of the buffer. That distinction is giving main character energy, so don't miss it 👑

Heads up: detection is about the 842 "END" template, not wherever the buffer happens to end. ikyk 🫶

🔥 RETURN 🔥

  • 0 on success 🎉
  • error on failure 💀

The olen parameter will contain the number of output bytes written on success, or 0 on error. So olen is literally carrying the receipts either way 🧾✨
