✨ NAME ✨

iw_cm_check_wildcard — if IP address is 0 then use original 🌸

---

🦋 SYNOPSIS 🦋

void iw_cm_check_wildcard (struct sockaddr_storage *pm_addr , struct
       sockaddr_storage *cm_addr , struct sockaddr_storage *cm_outaddr );

like, it returns void — no return value, she just does the thing and leaves 💅

🎀 ARGUMENTS 🎀

• pm_addr — a sockaddr containing the ip to check for wildcard 👀 this is the one we're side-eyeing to see if it's a wildcard.
• cm_addr — a sockaddr containing the actual IP address. the real one. the main character. 👑
• cm_outaddr — a sockaddr to set IP addr which leaving port. yes literally, it gets the IP set on it while the port is left alone 🫶

---

💖 DESCRIPTION 💖

so here's the vibe: it checks pm_addr for wildcard, and then it sets cm_outaddr's IP to the actual one, which is cm_addr. that's it, that's the whole function, and it ate. ✨
