sgp_verify_buffer(9)

okay so this is sgp_verify_buffer(9), straight outta the Kernel API Manual — and bestie, it does exactly what it says: it verifies the checksums of the data buffer words. no cap. 💅

✨ NAME ✨

sgp_verify_buffer — verify the checksums of the data buffer words. that's the whole assignment, and it ate. 🎀

🛠 SYNOPSIS 🛠

int sgp_verify_buffer (const struct sgp_data *data , union sgp_reading
*buf , size_t word_count );

🧠 ARGUMENTS 🧠

• data — SGP data. iconic input, no notes.
• buf — raw data buffer. the raw data buffer, as advertised.
• word_count — Num data words stored in the buffer, excluding CRC bytes. CRC bytes are literally not invited to this count, periodt. 🫶
