💅 folio_size(9) — the kernel API manual, bestie edition 🎀

okay so this is folio_size(9), straight out of the Kernel API Manual, and it's literally the glow-up of "how many bytes are in this folio" — the whole manual entry, no skips, no cap.

✨ NAME ✨

folio_size — the number of bytes in a folio. that's it. that's the whole gig. 💖

🌸 SYNOPSIS 🌸

size_t folio_size (const struct folio *folio );

like, you hand it a folio, it hands you back a size_t. iconic behavior honestly.

🦋 ARGUMENTS 🦋

  • folio — the folio. yes that's the whole description. she's the main character, she speaks for herself, iykyk 🫶

⭐ CONTEXT ⭐

okay listen up because this part actually matters bestie:

the caller should have a reference on the folio to prevent it from being split. like, keep her held tight so nobody tears her apart mid-whatever-you're-doing. 😭

it is not necessary for the folio to be locked. so like, chill on the locking, you don't need it here. 🧚

💜 RETURN 💜

the number of bytes in this folio. slay. that's the return value. 🔥
