cmd_db_read_addr(9)

💅 cmd_db_read_addr — Kernel API Manual, but make it make sense 💅

Okay bestie, so this is cmd_db_read_addr(9), straight out of the Kernel API Manual. It's a tiny little function with main character energy and honestly? It ate. Let's get into it. ✨

---

🌸 NAME 🌸

cmd_db_read_addr — the one where you ask the command db for a resource id's address. That's it, that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

u32 cmd_db_read_addr (const char *id );

Look at her. Literally so simple. u32 going in… no wait, u32 coming out, const char * going in. Slay. 💅

---

✨ ARGUMENTS ✨

• id — the resource id you're querying for an address. Yes queen, that's the whole argument. One (1) string. She's lowkey minimalist.

---

🔥 RETURN 🔥

• the resource address on success 🎉
• 0 on error 💀

That's the whole deal. If you get 0 back, it's giving "something went wrong," not "your address is zero." Just so we're clear, iykyk. 🫶

---

💖 DESCRIPTION 💖

So the way that this works is: you use it to retrieve a resource address based on a resource id. That's it. That's the function. She does exactly one (1) thing and she does it iconically. 🌈

No cap, sometimes the simplest functions are the most iconic ones. Periodt. 👑
