💫 iwpm_send_mapinfo(9) 💫

okay so bestie, welcome to the Kernel API Manual entry for iwpm_send_mapinfo — this is a kernel function that literally sends a client's local and mapped IPv4/IPv6 address info over to the user space port mapper. yeah. she's a messenger. she delivers. 🎀

---

✨ NAME ✨

iwpm_send_mapinfo — send local and mapped IPv4/IPv6 address info of a client to the user space port mapper 💌

---

🌸 SYNOPSIS 🌸

int iwpm_send_mapinfo(u8 nl_client, int iwpm_pid);

like that's the whole signature, she's not complicated, she's just booked and busy 🦋

---

🫶 ARGUMENTS 🫶

• nl_client — the index of the netlink client. that's the little number that tells everyone which netlink client we're talking about, no cap 💅
• iwpm_pid — the pid of the user space port mapper. yes, the actual process id of the port mapper hanging out in userspace, she needs to know who to send to 🧚

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: if it works out, this returns the number of sent mapping info records. that's the whole plot. she goes, she sends, she tells you how many mapping info records made it out the door. iconique behavior honestly 👑

ngl there's no long dramatic story here — the return value is the description. if successful, you get the count of mapping info records that were sent. that's it. that's the tea ☕
