🎧 snd_rawmidi_receive(9) — Kernel API Manual 🎧

Okay bestie, welcome to the snd_rawmidi_receive(9) page from the Kernel API Manual. This function is highkey a tiny main character energy moment whose whole plot is receiving the input data from the device, and I’m obsessed. No cap. Vibe check: pass. Let’s go 💖✨

🌸 NAME 🌸

snd_rawmidi_receive — receive the input data from the device. Periodt. That’s the name and that’s the assignment 💅

✨ SYNOPSIS ✨

int snd_rawmidi_receive (struct snd_rawmidi_substream *substream , const unsigned char *buffer , int count );

💅 ARGUMENTS 💅

• substream — the rawmidi substream. It’s literally the rawmidi substream, iykyk.
• buffer — the buffer pointer. Not me explaining it exactly as the buffer pointer, but that’s the tea 🍓.
• count — the data size to read. That’s the data size to read, fr fr.

🦋 DESCRIPTION 🦋

This function reads the data from the internal buffer. That’s it. It’s giving “simple and iconic.” The way that it just reads the data from the internal buffer? Ate and left no crumbs. Slay 🦋✨

🎀 RETURN 🎀

It returns the size of read data, or a negative error code on failure. So the return vibe is either the size of read data — happy little read — or a negative error code on failure — sad, tragic, handle-with-care energy 😭

Cute footer-core sign-off, bestie: source ./sound/core, date October 2026, and the snd_rawmidi_receive(9) manual itself. That’s a wrap — go off and receive that input data 💅🎀✨
