    char          **ether_addr

💖 DESCRIPTION 💖

nozzle_get_mac bestie it's giving "tell me my mac address" and honestly? same energy.

• nozzle — pointer to the nozzle struct. your main character. the handle you're working with 🫶
• ether_addr — pointers to string containing the current mac address. yes, a pointer to a pointer, she's fancy like that ✨

⚠️ important bestie, do NOT sleep on this: the string is malloc'ed, so the caller needs to free this buffer. like, it's YOUR buffer now. you gotta clean up after yourself, that's the rule 💀 no memory leaks in this house.

🎀 RETURN VALUE 🎀

• 0 — on success. slay. we ate. 👑
• -1 — on error, and errno is set. sad girl hours 😭 go check errno, she's telling you what went wrong.
