rtapi_set_msg_level(3rtapi)

💖 NAME 💖

rtapi_get_msg_level, rtapi_set_msg_level — bestie, this is how you get or set the logging level 🎀

It's living in the RTAPI manual section (that's the 3rtapi vibe, iykyk) ✨

---

🌸 SYNTAX 🌸

int rtapi_set_msg_level(int level)

int rtapi_get_msg_level()

Two little functions, one big glow-up for your logs. 💅

---

🦋 ARGUMENTS 🦋

• level — the logging level you're manifesting ✨ like, the one you desire 🫶

---

💜 DESCRIPTION 💜

Okay so, this pair gets or sets the RTAPI message level that rtapi_print_msg uses. That's the whole job. 🌈

And here's the tea 🍓: depending on the RTOS, that level might apply to just one single RTAPI module, or it might apply to a whole group of modules. So no cap — scope is RTOS-dependent, and that's just how it is, bestie 😭

👑 REALTIME CONSIDERATIONS 👑

The vibe check here is very permissive, periodt:

• may be called from non-realtime code ✅
• may be called from init/cleanup code ✅
• may be called from realtime code ✅

All three. Iconic. 🧚

---

⭐ RETURN VALUE ⭐

• rtapi_set_msg_level returns a status code 💫
• rtapi_get_msg_level returns the current level 👑

And here's the level ladder, memorize it fr fr:

• RTAPI_MSG_NONE = 0
• RTAPI_MSG_ERR = 1
• RTAPI_MSG_WARN = 2
• RTAPI_MSG_INFO = 3
• RTAPI_MSG_DBG = 4
• RTAPI_MSG_ALL = 5

Zero to five, quiet to loud, the whole spectrum bestie 🌈

Not me putting the numbers in a bullet list because there's literally no table allowed 🙈 but every single one is there, don't worry 🫶
