pack_fields_u8(9)

✨ pack_fields_u8(9) — Kernel API Manual, bestie ✨

okay so we’re in the Kernel API Manual, and the main character is pack_fields_u8(9). it packs an array of fields, and the vibe check is: use the macro, not this direct call. iykyk 💅

🦋 NAME 🦋

pack_fields_u8 — pack array of fields. literally what it says on the tin, no cap. 💖

🌈 SYNOPSIS 🌈

void pack_fields_u8 (void *pbuf , size_t pbuflen , const void *ustruct ,
       const struct packed_field_u8 *fields , size_t num_fields , u8 quirks );

🎀 ARGUMENTS 🎀

• pbuf — pointer to a buffer holding the packed value. it’s giving “packed value lives here” energy. 💖
• pbuflen — the length in bytes of the packed buffer pointed to by pbuf. yes, bytes, bestie. 📏
• ustruct — pointer to a 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 the type match is on you, not on the function.
• fields — array of packed_field_u8 field definition. They must not overlap. no overlap, periodt. 🚫✨
• num_fields — length of fields array. count ’em. 🔢
• quirks — a bit mask of QUIRK_LITTLE_ENDIAN, QUIRK_LSW32_IS_FIRST and QUIRK_MSB_ON_THE_RIGHT. bit-mask moment, slay. 🎛️

💫 DESCRIPTION 💫

Use the pack_fields macro instead of calling this directly. that’s the instruction, and it’s important — take the macro route, bestie. 🫶

real talk: don’t call this one directly; use the pack_fields macro instead. 💅
