seq_buf_putmem(9)

💾 NAME 💾

okay bestie, welcome to the Kernel API Manual page for seq_buf_putmem(9) — literally the function that lets you write raw data into the sequence buffer. No cap.

seq_buf_putmem - write raw data into the sequence buffer

---

📜 SYNOPSIS 📜

int seq_buf_putmem (struct seq_buf *s , const void *mem , unsigned int
       len );

---

🎀 ARGUMENTS 🎀

• s — the seq_buf descriptor, aka the buffer's main-character passport 💅
• mem — the raw memory you're copying into the buffer 🫶
• len — the length of that raw memory you're copying, in bytes, exactly ✨

---

💖 DESCRIPTION 💖

okay so sometimes you've got raw memory that needs to be written into the buffer, and strcpy is simply not gonna work for that. Not the vibe. Using this function is literally how you handle those cases. That's the whole reason it exists, bestie 🦋

---

🔁 RETURN 🔁

0 on success, -1 on overflow. That's it, that's the tea ☕
