💅 seq_buf_putc — the Kernel API Manual girlie's edition ✨

okay so bestie, welcome to the seq_buf_putc page from the Kernel API Manual 🎀 — it's giving "tiny function, big responsibility," and honestly? iconic.

✨ NAME ✨

seq_buf_putc — sequence printing of a simple character 🦋

---

🌸 SYNOPSIS 🌸

int seq_buf_putc (struct seq_buf *s , unsigned char c );

---

💖 ARGUMENTS 💖

• s — your seq_buf descriptor, aka the little buffer situation we're working with 🫶
• c — the simple character you wanna record. one (1) single char. that's it. that's the vibe 💅

---

🌈 DESCRIPTION 🌈

So what does it do? It copies a single character into the sequence buffer. literally just one character. no cap, that's the whole plot 🍓

---

⭐ RETURN ⭐

• zero on success — slay, we ate 💅
• -1 on overflow — 😭 the buffer said "no more room bestie"
