okay so this is the Kernel API Manual entry for sm3_update, and it’s literally here to update an SM3 context with message data ✨💅

💖 NAME

sm3_update — update an SM3 context with message data 🦋

✨ SYNOPSIS

void sm3_update (struct sm3_ctx *ctx , const u8 *data , size_t len );

🎀 ARGUMENTS

• ctx — the context to update, bestie; it must have been initialized 💅
• data — the message data 🌸

not me being dramatic, but ctx must have been initialized before you call this — that’s a real requirement on the page, not a vibe suggestion 🫶

🦋 DESCRIPTION

This can be called any number of times ✨. That’s the whole description, no cap 😭💖

🌈 CONTEXT

Any context. That’s the vibe check, and it passed 👑🌈
