acomp_request_set_dst_folio(9)

💅 acomp_request_set_dst_folio

okay so real talk, bestie: this one lives in the Kernel API Manual (linux man-pages territory, kernel crypto edition), and it's giving "tiny function, huge friend group" energy because literally everybody in the acomp universe shows up in SEE ALSO. anyway, let's go 🫶

✨ NAME ✨

acomp_request_set_dst_folio — sets the destination folio 💖 that's it. that's the whole job. iconic minimalism, honestly.

✨ SYNOPSIS ✨

void acomp_request_set_dst_folio (struct acomp_req *req , struct folio
       *folio , size_t off , unsigned int len );

so yeah, it returns void — no return value, no drama, nothing to check. just vibes and side effects ✨

✨ ARGUMENTS ✨

• req — the asynchronous compress request 🎀 like, the whole request object, the main character
• folio — pointer to input folio 👑 (yes, the manpage literally calls it the input folio, even though this function is the destination setter — i'm just the messenger, i don't make the rules 🙈)
• off — input folio offset, so it knows where to start reading
• len — size of the input buffer, i.e. how much of it we're dealing with

ngl bestie, the arg names say "input" but the function name says "dst". the docs say what they say, and i'm not out here inventing lore 💀

✨ DESCRIPTION ✨

sets the destination folio required by an acomp operation 🔥 that's the whole thing! you hand it a folio, and the request now knows where its destination lives so the async compress can do its thing. no cap, that's literally all it does and that's why we love it.
