parse_protocol_change(9)

💖 NAME 💖

okay bestie, welcome to the parse_protocol_change(9) page from the Kernel API Manual — the icon itself, parse_protocol_change, and its whole job is literally parses a protocol change request ✨

---

🎀 SYNOPSIS 🎀

int parse_protocol_change (struct rc_dev *dev , u64 *protocols , const char *buf );

---

🦋 ARGUMENTS 🦋

• dev — the rc_dev device, main character energy fr fr
• protocols — pointer to the bitmask of current protocols, lowkey the whole mood board
• buf — pointer to the buffer with a list of changes, aka the group chat receipts 📨

---

🌸 DESCRIPTION 🌸

okay so here's the tea, no cap — this function reads what you wrote and updates the protocol mask accordingly:

• Writing "+proto" will add a protocol to the protocol mask 💅
• Writing "-proto" will remove a protocol from the protocol mask 🫶
• Writing "proto" will enable only "proto" — exclusive era 👑
• Writing "none" will disable all protocols 💀

and then it returns the number of changes performed or a negative error code — so like, keep an eye on that return value bestie, negative means something went sideways 😭🔥
