💅 cdns_rs485_rx_callback(9) — like, the Kernel API Manual page, bestie ✨

okay so bestie, welcome to the glow-up edition of cdns_rs485_rx_callback(9) 🎀 this is the Kernel API Manual entry and it's genuinely so niche and so iconic of it. it's the timer rx callback handler for rs485 — think of it as the little timer-driven moment where the receive side of rs485 gets its callback moment on stage 👑 main character energy fr fr.

🌸 NAME 🌸

cdns_rs485_rx_callback — Timer rx callback handler for rs485. that's the whole vibe. it handles the rx callback off a timer, for rs485. no cap 💅

✨ SYNOPSIS ✨

here's exactly how you call it, don't touch the characters, i'm serious 🙈:

enum hrtimer_restart cdns_rs485_rx_callback (struct hrtimer *t );

she returns an enum hrtimer_restart, she takes one pointer, and she ate 🔥

🦋 ARGUMENTS 🦋

one argument, one. keep up 💖

  • t — Handle to the hrtimer structure. that's it, that's the whole parameter list. it's giving minimalism, it's giving "i only need one thing to slay" ✨

💜 SEE ALSO 💜
