polyval_init(9)

✨ NAME ✨

okay so this is the polyval_init(9) page from the Kernel API Manual, and it's literally about one thing: setting up a POLYVAL context for a brand-new message. icon behavior tbh.

polyval_init — Initialize a POLYVAL context for a new message 💖

🛠️ SYNOPSIS 🛠️

void polyval_init (struct polyval_ctx *ctx , const struct polyval_key *key );

💅 ARGUMENTS 💅

• ctx — the context you're initializing. this is the main character getting set up bestie ✨
• key — the key to use. important heads-up: a pointer to the key is saved in the context, so the key must live at least as long as the context. no cap, do not let that key dip out early 😭
