💅 ir_raw_gen_pulse_space(9) — it's giving Kernel API Manual realness

okay bestie, so this is a page about ir_raw_gen_pulse_space — a lil function that literally just generates pulse and space raw events. that's it, that's the whole job, and honestly? iconic. ✨

🎀 NAME 🎀

ir_raw_gen_pulse_space — generate pulse and space raw events. no cap, that's the entire mission statement. 🫶

---

🌸 SYNOPSIS 🌸

int ir_raw_gen_pulse_space (struct ir_raw_event **ev , unsigned int *max
, unsigned int pulse_width , unsigned int space_width );

look at her. four args. clean. she knows what she's doing. 💅

---

🦋 ARGUMENTS 🦋

so here's the breakdown of everyone invited to the function party:

• ev — a pointer to a pointer to the next free raw event. every time a raw event gets written, this bad boy gets incremented. she moves with the vibes. ⭐
• max — a pointer to how many raw events are available in the buffer. every time a raw event gets written, it gets decremented. it's literally doing a countdown, main character energy fr fr. 🔥
• pulse_width — the width of the pulse, measured in ns. that's nanoseconds bestie, we're operating on a whole different time scale here. 💜
• space_width — the width of the space, also in ns. pulse's counterpart. the calm to the chaos. the other half of the duo. 🌈

---

👑 RETURN 👑

• 0 — success! slay! everything worked and we're all thriving. 💖
• -ENOBUFS — this is the "there isn't enough buffer space to write both raw events" situation. 😭 when this happens? max events will have been written — so like, some stuff made it in, but not all of it. a partial serve. half-ate. 🙈

ngl, lowkey important detail: when you get -ENOBUFS back, max events will have been written. so don't act brand new when some of your data is already sitting in the buffer, okay? 🎀

okay that's the whole page and honestly she ate — every option, every caveat, every reference, all of it present and accounted for. 💅✨

go touch some infrared, bestie. and remember: this page lives in ./drivers/media/rc and the manual's version stamp is October 2026 — a whole future date, very ahead of its time, very fairy-core, very 🧚‍♀️🍓💜 — while the page itself is ir_raw_gen_pulse_space(9) from the Kernel API Manual. bye diva! 🦋🌸💖
