💅 usb_gadget_s...emote_wakeup(9) — like, the remote wakeup switch, bestie

okay so real talk: this is a page from the Kernel API Manual, and the star of the show is usb_gadget_set_remote_wakeup. it's short, it's sweet, it's literally two arguments and a return code. let's get into it ✨

🦋 NAME 🦋

usb_gadget_set_remote_wakeup — this one configures the device remote wakeup feature. that's it. that's the whole vibe. 💫

---

🌸 SYNOPSIS 🌸

int usb_gadget_set_remote_wakeup (struct usb_gadget *gadget , int set );

yes queen, that's the entire signature, no cap 👑

---

🎀 ARGUMENTS 🎀

• gadget — the device you're configuring for remote wakeup. it's giving "main character," iykyk 🫶
• set — the value you wanna configure. that's the whole assignment, fr fr.

---

💖 DESCRIPTION 💖

okay so here's the tea, and it's genuinely this simple:

set it to one to enable the remote wakeup feature, and set it to zero to disable it. slay. no in-between, no secret third option. 🙈

and what does it give back? it returns zero on success, else a negative errno. so like, zero = we ate 💅, negative = something went sideways and you're getting an errno back. periodt.
