💅 ni_assign_device_routes(9) — the Kernel API Manual glow-up ✨

okay so bestie, this is ni_assign_device_routes(9) from the Kernel API Manual, and it's literally the function that assigns the proper lookup table for NI signal routing to the specified NI device. no cap, it's giving “route matchmaker” energy. 🫶

---

✨ NAME ✨

ni_assign_device_routes — assign the proper lookup table for NI signal routing to the specified NI device. periodt. 💖

🛠 SYNOPSIS 🛠

this is the whole signature, bestie, and yes you need every bit of it:

int ni_assign_device_routes (const char *device_family , const char
       *board_name , const char *alt_board_name , struct ni_route_tables
       *tables );

🎀 ARGUMENTS 🎀

• device_family — device family name, which determines the route values. 👑
• board_name — board name, which determines the set of routes. 🦋
• alt_board_name — optional alternate board name to try on failure. like a backup bestie. 🙈
• tables — pointer to the assigned routing information. this is where the routing info goes. 📌

💅 DESCRIPTION 💅

okay so here's the tea: it finds the route values for the device family and the set of valid routes for the board. if valid routes could not be found for the actual board name, and an alternate board name has been specified, it tries that one. 🎀

⚠️ on failure, the assigned routing information may be partially filled — for example, with the route values but not the set of valid routes. so yeah, it's not guaranteed to be a full clean fill, bestie. 💀

🔥 RETURN 🔥

• -ENODATA — if assignment was not successful. 😭
• 0 — if successful. slay. ✨
