✨ rave_sp_eeprom_access(9) ✨

okay bestie, so this one is a page from the Kernel API Manual and it's literally about poking at EEPROM data 👑 — like, the function that just gets in there and reads or writes whatever you want, wherever you want. no page-alignment drama, no page-size nonsense. we love a flexible icon 💅

---

🌸 SYNOPSIS 🌸

int rave_sp_eeprom_access (struct rave_sp_eeprom *eeprom , enum
rave_sp_eeprom_access_type type , unsigned int offset , u8 *data ,
unsigned int data_len );

like yes, that's the whole signature, write it down, memorize it, put it on a vision board 🎀

💖 ARGUMENTS 💖

• eeprom — the EEPROM device you're trying to access. your main character. the one you're talking to 🫶
• type — the access type you wanna perform, i.e. read or write. pick your vibe ✨
• offset — where inside the EEPROM you're poking around, offset-style 💫
• data — the data buffer. this is where the goods go, bestie 🍓
• data_len — size of that data buffer. how much room you've got 👑

---

🦋 DESCRIPTION 🦋

so basically: this function performs a generic access — either a read or a write — at an arbitrary offset (and no, it does not need to be page aligned, we're not like that 🙈) and of arbitrary length (nope, it is not constrained by the EEPROM page size either — she's free 💅).

it returns zero in case of success, or a negative error code in case of failure 😭 so like, check the return value, obviously.

fr fr, zero = slay, negative = something went 💀
