gadget_is_otg(9)

💖 NAME 💖

okay so bestie, welcome to gadget_is_otg(9) from the Kernel API Manual 💅 this one is literally just: it returns true iff the hardware is OTG-ready. that’s the whole entire superhero origin story. ✨

🎀 SYNOPSIS 🎀

int gadget_is_otg (struct usb_gadget *g );

🌸 ARGUMENTS 🌸

• g — controller that might have a Mini-AB connector 👀✨

🦋 DESCRIPTION 🦋

bestie, this is a runtime test — yes, runtime, not a vibe you can just assume once and then forget about. why? because kernels with a USB-OTG stack sometimes run on boards which only have a Mini-B (or Mini-A) connector. so it does the check at runtime, periodt. 💅
