FUNCTION::PROC_MEM_D(3stap)

💖 function::proc_mem_data — the page-counting queen of process memory 💖

okay so bestie, we're in the Memory Tapset section of the SystemTap Tapset Reference, and the page we're reading is function::proc_mem_data(3stap). yes it's a mouthful, no you don't have to say it out loud. 🫶

---

🌸 NAME 🌸

function::proc_mem_data — program data size (data + stack) in pages

like. it counts pages. data plus stack. that's the whole vibe. ✨

---

🦋 SYNOPSIS 🦋

1) proc_mem_data:long()

2) proc_mem_data:long(pid:long)

two flavours, same energy. one takes a pid, one is just out here doing its own thing. 💅

---

🎀 ARGUMENTS 🎀

• pid — the pid of process to examine 👀

that's it. that's the argument. she's simple, she's iconic.

✨ DESCRIPTION ✨

so there's two versions and you gotta know which one you're calling, fr fr:

1. Returns the current process data size (data + stack) in pages, or zero when there is no current process or the number of pages couldn't be retrieved. 😭 (yes, zero. that's the "bestie I literally could not" fallback.)
2. Returns the given process data size (data + stack) in pages, or zero when the process doesn't exist or the number of pages couldn't be retrieved. 💀

ngl the zero is doing a lot of heavy lifting here — it's the answer both when there's genuinely nothing and when the page count just couldn't be retrieved. don't be out here assuming zero means "no memory", okay? 🙈
