like, literally just one line. one. single. line. 🎀

int snd_info_get_line (struct snd_info_buffer *buffer , char *line , int
len );

that's the whole signature, no cap. copypaste responsibly 💅

---

🦋 ARGUMENTS 🦋

• buffer — the procfs buffer. it's the source, the main character, the place we're reading from 🫶
• line — the buffer to store. that's where the string ends up, so it can live its best life 💖
• len — the max. buffer size. the vibe check on how much we're allowed to write, so nothing overflows 😭

---

💜 DESCRIPTION 💜

Reads one line from the buffer and stores the string.

that's it. that's the function. it reads one line, it stores the string in line, and it goes about its day. iconic behaviour honestly ⭐

Zero if successful, or 1 if error or EOF.

so like — 0 = we ate 💅, 1 = error or end-of-file, no in between bestie 🌈
