dmmp_...d_get(3)

💖 dmmp_path_group_id_get — the libdmmp manual, bestie edition 💖

okay so you're in the Device Mapper Multipath API docs, aka the libdmmp Manual, and today's main character is a lil function called dmmp_path_group_id_get. she's small. she's simple. she ATE. let's go 🦋

---

✨ NAME ✨

dmmp_path_group_id_get — Retrieve path group ID. (yes that's it, that's the whole job, and she does it flawlessly 💅)

---

🌸 SYNOPSIS 🌸

uint32_t dmmp_path_group_id_get (struct dmmp_path_group *dmmp_pg);

---

🎀 ARGUMENTS 🎀

• dmmp_pg — Pointer of 'struct dmmp_path_group'. and listen, bestie, listen: if this pointer is NULL, your program will be terminated by assert. like, not a gentle error return, not a cute little -1, just gone. 💀 so pls pls pls pass a real pointer. fr fr.

---

🫶 DESCRIPTION 🫶

Retrieve the path group ID — the way that this ID is literally the thing you feed into a command to switch the active path group. iconic. here's the move:

multipathd -k'switch multipath mpathb group $id'

so you grab the ID with this function, and then $id there is where it goes. that's the whole pipeline, no cap. 🧚

---

⭐ RETURN ⭐

uint32_t.

(that's the type. that's the vibe. a uint32_t, and nothing else. periodt. 👑)

---

ngl the one thing to remember: NULL in = assert = program terminated. keep dmmp_pg valid and you're golden. 🌈

---

and that's the page, bestie!! this was the dmmp_path_group_id_get page from the Device Mapper Multipath API — libdmmp Manual, dated June 2025. mwah, go switch some path groups, you absolute legend 💖🎀✨
