seq_buf_putmem_hex(9)

💅 seq_buf_putmem_hex(9) — the Kernel API Manual era 🎀

okay so bestie, welcome to the seq_buf_putmem_hex(9) page — it lives in the Kernel API Manual and honestly it's giving "small function, big main character energy" ✨

---

🌸 NAME 🌸

seq_buf_putmem_hex — write raw memory into the buffer in ASCII hex 🦋

---

✨ SYNOPSIS ✨

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

literally the whole signature, no crumbs left behind 💖

---

🎀 ARGUMENTS 🎀

• s — the seq_buf descriptor, aka the buffer bestie that's holding all your stuff 🫶
• mem — the raw memory you want written as its hex ASCII representation, like we're translating it into hex-speak 🔥
• len — how long the raw memory you're copying is, in bytes. count them, don't guess ngl 💀

---

👑 DESCRIPTION 👑

so this one is similar to seq_buf_putmem — except instead of just copying the raw memory straight into the buffer, it writes the ASCII representation of it in hex characters 💅

that's the whole vibe: same energy as seq_buf_putmem, but make it hex ✨

---

⭐ RETURN ⭐

• zero on success 🎉
• -1 on overflow 😭 (the buffer said no ma'am)
