NOZZLE_ADD_IP(3)

💖 NOZZLE_ADD_IP 💖

okay so bestie, welcome to nozzle_add_ip from the Kronosnet Programmer's Manual — section 3, the library-calls girlies ✨. She's literally the equivalent of ip addr or ifconfig <ipaddress/prefix>, but make it a function call 🎀

---

✨ NAME ✨

nozzle_add_ip — the equivalent of ip addr or ifconfig <ipaddress/prefix> 💅

---

🌸 SYNOPSIS 🌸

#include <libnozzle.h>

int nozzle_add_ip(
    nozzle_t      nozzle,
    const char   *ipaddr,
    const char   *prefix
);

---

🦋 DESCRIPTION 🦋

nozzle_add_ip ✨

• nozzle — a pointer to the nozzle struct. she's the main character, obviously 👑
• ipaddr — a string holding either an IPv4 or an IPv6 address. okay so IMPORTANT thing, no cap: Linux will automatically remove any IPv6 addresses from an interface with MTU < 1280 😭. but don't panic, because libnozzle will cache those IPs and re-instate them when MTU is > 1280 🫶. also, MTU must be set via nozzle_set_mtu for the IPv6 to be re-instated — like, that's the only way, periodt 💅
• prefix — 24, 64, or literally any valid network prefix for the address you asked for 🌈

---

⭐ RETURN VALUE ⭐

• 0 on success 🎉
• -1 on error, and errno gets set 😔
