unpack_fields_u8(9)

📦 version 7.3.1, in nixpkgs unstable

💅 unpack_fields_u8(9) — bestie's guide to the Kernel API Manual

okay so bestie, welcome to unpack_fields_u8(9) from the Kernel API Manual — it's giving "unpack that array of fields" energy, and we're gonna get into it 💖

✨ NAME ✨

unpack_fields_u8 — Unpack array of fields. literally what it says on the tin, no cap 🎀

✨ SYNOPSIS ✨

void unpack_fields_u8 (const void *pbuf , size_t pbuflen , void *ustruct
, const struct packed_field_u8 *fields , size_t num_fields , u8 quirks
);

✨ ARGUMENTS ✨

  • pbuf — Pointer to a buffer holding the packed value. that's the tucked-in, still-packed version, bestie 🦋
  • pbuflen — The length in bytes of the packed buffer pointed to by pbuf. gotta know how many bytes we're working with 💅
  • ustruct — Pointer to CPU-readable structure holding the unpacked value. It is expected (but not checked) that this has the same data type as all struct packed_field_u8 definitions. so like… nobody's double-checking that for you, bestie — be careful out there 😭
  • fields — Array of packed_field_u8 field definitions. They must not overlap. seriously, no overlapping, that's the rule 🌸
  • num_fields — Length of fields array. just how many field definitions we're dealing with ✨
  • quirks — A bit mask of QUIRK_LITTLE_ENDIAN, QUIRK_LSW32_IS_FIRST and QUIRK_MSB_ON_THE_RIGHT. all the endianness and bit-order vibes in one little mask 👑

✨ DESCRIPTION ✨

Use the unpack_fields macro instead of calling this directly. like, bestie, this is the backstage version — the macro is the main character here 💅

✨ SEE ALSO ✨

slay, that's the whole page 💜 stay packed, stay iconic, and remember: the macro is your bestie, not the direct call ✨
