FUNCTION::TCPMIB_FIL(3stap)

💖 FUNCTION::TCPMIB_FIL — SNMP Information Tapset ✨

okay bestie, you're in the 3stap section of the manual, and this is the SNMP Information Tapset era. let's get into it 🫶

---

🌸 NAME 🌸

function::tcpmib_filter_key — the default filter function for tcpmib.* probes. it's giving gatekeeper, but in a helpful way 💅

---

✨ SYNOPSIS ✨

tcpmib_filter_key:long(sk:long,op:long)

---

🎀 ARGUMENTS 🎀

• sk — a pointer to the struct sock that's being acted on. like, the socket in question, the main character of this whole operation 💫
• op — the value that gets counted if sk passes the filter. so it's waiting in the wings, and it only gets its moment if the filter says yes ✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea: this function is a default filter function. the user can literally replace it with their own, no cap — it's yours to swap out.

when you do supply your own filter function, it returns an index key based on the values inside sk.

and here's the part you cannot miss: if the return value is 0, that means this particular sk should not be counted. zero = not invited to the party 🙈. periodt.
