spinand_fact_otp_read(9)

💅 spinand_fact_otp_read — bestie, we're reading from the OTP area

okay so picture this: it's a kernel API manual page, manual name is Kernel API Manual, and the star of the show is spinand_fact_otp_read(9). She's a function, she reads from the OTP area, and honestly? iconic. let's get into it ✨

🌸 SYNOPSIS 🌸

int spinand_fact_otp_read (struct spinand_device *spinand , loff_t ofs ,
       size_t len , size_t *retlen , u8 *buf );

like, that's the whole signature. no cap, that's it. 🎀

🦋 ARGUMENTS 🦋

bestie, she takes five (5) things and you gotta get every single one right or it's giving undefined chaos:

• spinand — the spinand device itself. your main character. the whole vibe depends on her 💖
• ofs — the offset to read from. where we're starting, iykyk ✨
• len — the number of data bytes to read. how much we're grabbing 🎀
• retlen — a pointer to the variable where the number of read bytes gets stored. she reports back, we love a communicative queen 🫶
• buf — the buffer where the read data goes to live. her little home 🌸

🔥 RETURN 🔥

0 on success, an error code otherwise. that's it. zero means slay, anything else means something went sideways 😭 keep an eye on it fr fr.
