TH_LOG(9)

💅 TH_LOG 💅

okay so welcome to the TH_LOG page, from the Kernel API Manual, and bestie it is short but it's also kind of a whole vibe 🫶

---

✨ NAME ✨

TH_LOG — and that's literally it, the description field is blank in the original, so we are not inventing one, no cap 💀

---

🌸 SYNOPSIS 🌸

TH_LOG (fmt , ... );

---

🦋 ARGUMENTS 🦋

• fmt — the format string, the main character of this whole operation ✨
• ... — optional arguments, aka the plus-ones 🎀

---

👑 DESCRIPTION 👑

TH_LOG(format, ...)

So this is the optional debug logging function that's available for use in tests 💖 Like, it's a logging helper, it's optional, and it lives to serve your tests — that's the entire lore.

Logging may be enabled or disabled by defining TH_LOG_ENABLED, iykyk. For example:

#define TH_LOG_ENABLED 1

And if you don't provide any definition at all? Then logging is enabled by default — no setup, no stress, it just works 🌸
