FUNCTION::FTRACE(3stap)

💖 FUNCTION::FTRACE 💖

okay bestie, so this is a page from the Logging Tapset family, and it lives in manual section 3stap — that's the SystemTap tapset reference, iykyk 🫶

✨ NAME ✨

function::ftrace — the little function that sends a message straight to the ftrace ring-buffer 🌸

---

🦋 SYNOPSIS 🦋

ftrace(msg:string)

---

🎀 ARGUMENTS 🎀

• msg — the formatted message string, periodt. it's a string, it's formatted, that's the whole vibe 💅

---

👑 DESCRIPTION 👑

so here's the tea, bestie ☕

if the ftrace ring-buffer is configured & available (yes, both — the & is doing real work here), then your message shows up over at:

/debugfs/tracing/trace

that's your spot to go look at it. go, look, slay 🌈

but if it's not configured and available? then lowkey the message may just get quietly dropped 😭 no error, no drama, no nothing — it just ✨ evaporates ✨. so don't be surprised if you go looking and there's nothing there.

one more thing: an implicit end-of-line gets added. so you don't gotta add your own newline, the function's already got you 🫶
