ipr_show_fw_version(9)

💅 NAME

okay so bestie, this is ipr_show_fw_version(9) — yes the (9) is the section, that's the Kernel API Manual vibe — and its whole entire job is showing the firmware version. that's it. that's the function. she's an icon, she does one thing, and she slays it ✨

---

🎀 SYNOPSIS

ssize_t ipr_show_fw_version (struct device *dev , struct
       device_attribute *attr , char *buf );

like, literally that's the whole signature 💖 keep it exactly like that, no cap.

---

🦋 ARGUMENTS

• dev — a class device struct. the class device struct, actually. she's the main character here 👑
• attr — the device attribute... which is unused 🫶 so yeah, she's just here for the vibes, she shows up and does nothing and honestly? relatable 🙈
• buf — the buffer. the place where the printing happens. no thoughts, just buffer 🎀

---

🌸 DESCRIPTION

the return value is: the number of bytes printed to buffer 💫 that's the whole description bestie, she's a short queen and she's not gonna waste your time. iykyk.

also go look at the Kernel file ./drivers/scsi/ipr.c — that's where the actual code lives, go be nosy 👀
